Airport Car Rental in Bulgaria
Bulgaria has three international airports with rental car presence, and which one you use shapes your entire trip. Sofia Airport is the year-round hub with the best selection and pricing. Varna and Burgas airports on the Black Sea coast are summer-heavy, handling charter flights from across Europe and charging seasonal premiums. We have rented at Sofia and Burgas, and the experiences were different enough to warrant separate advice.
The three-airport system is actually an advantage: you can pick up at Sofia and drop off at a coastal airport (or vice versa) for a one-way fee, avoiding the return drive. For a Sofia-to-coast itinerary or a coast-to-Sofia loop, this works well. The country is compact enough that you will cover the whole thing in a week and still feel like you missed half of it.
Sofia Airport (SOF) Car Rental
Sofia Airport is 10 km east of the city center, with two terminals. Terminal 1 handles some domestic and regional flights. Terminal 2 handles most international flights — virtually all rental agencies are here.
Rental desk locations: Car rental counters are in the arrivals hall of Terminal 2, on the ground floor after exiting customs and baggage claim. They are arranged in a row, clearly visible from the arrivals exit.
Operating hours: Most desks operate from 06:00 to midnight. For late-night or early-morning arrivals, confirm with your specific agency in advance — some offer 24/7 service with an after-hours fee of 20-40 BGN ($11-22).
The pickup process:
- Exit customs into the arrivals hall
- Car rental desks are directly ahead on the right side of the hall
- Present booking confirmation, passport, driving license, and IDP (if applicable)
- Complete paperwork and insurance discussion (10-15 minutes)
- Walk to the car park adjacent to the terminal (2-3 minutes)
- Inspect the vehicle, photograph all panels and interior
- Drive out on the E871 ring road toward Sofia or directly onto A1 toward Plovdiv
From the airport to Sofia city center: Take the ring road (E871) west, following signs for Sofia Centrum. The drive takes 15-25 minutes depending on traffic. No toll or vignette needed for this specific ring-road section. Traffic can be heavy during morning rush (07:30-09:30) — from the airport, you are entering Sofia’s eastern commute.
From the airport toward the A1 (Plovdiv/Burgas direction): Follow signs for Plovdiv/A1 from the airport exit. The junction with the A1 is approximately 8 km south of the airport. You need the vignette before entering the motorway — if you did not buy it online (bgtoll.bg), do so at the airport fuel station.

Driving License Requirements
EU/EEA license holders drive on their national license with no additional documentation. For non-EU licenses — US, UK, Canada, Australia — an International Driving Permit (IDP) is officially required alongside your national license. Major international agencies at Sofia Airport routinely accept US and UK licenses without an IDP, but having one prevents any friction at police checkpoints on rural roads, where a local officer following the letter of the law may take a different view.
| License Origin | IDP Required? | Notes |
|---|---|---|
| EU/EEA | No | National license sufficient |
| UK | Technically yes | International agencies often waive; carry one for safety |
| US/Canada | Yes | AAA/CAA issues for $20, in person, 5 minutes |
| Australia/NZ | Yes | NRMA and equivalent clubs issue them |
| Russia/Ukraine | Yes | Additional scrutiny at smaller agencies; IDP strongly recommended |
Minimum rental age: 21 at most agencies, with a young driver surcharge of 5-15 BGN ($3-8) per day for drivers under 25. At least one year of driving experience required. Some premium vehicle classes require age 25+.
Agencies at Sofia Airport
International Agencies
Europcar has the most organized counter at SOF with a well-maintained fleet of European vehicles. Economy from 40-60 BGN ($22-33) per day in high season. Cross-border driving to Romania (now Schengen-free) and most EU neighbors is typically included. Serbia and Turkey require additional documentation — if you are planning a cross-Balkan itinerary, declare the countries at booking rather than at pickup.
Sixt is competitive on pricing with a modern fleet. Economy from 35-55 BGN ($19-30) per day. Good automatic transmission availability — relevant since automatics are notably less common in Bulgarian rental fleets than in the US or UK. The Sixt desk typically has shorter queues than Europcar at busy arrival times.
Hertz offers a full range from economy to SUV and luxury. Economy from 40-60 BGN ($22-33) per day. Good for travelers who want consistent international documentation and dispute resolution processes that follow a known European standard.
Avis/Budget (same parent company) have adjacent counters at SOF. Budget is cheaper, Avis has a broader fleet. Economy from 38-55 BGN ($21-30) for Budget, 40-60 BGN for Avis per day. If the price difference between the two is less than 10 BGN per day, we usually go with Avis for the fleet quality — the consistency on longer Bulgarian road trips makes a difference.
Enterprise has a growing presence at SOF. Competitive rates and fleet quality. Economy from 38-55 BGN ($21-30) per day.
Local Agencies
Top Rent a Car is Bulgaria’s largest domestic rental company and one of the best-regarded locally. Well-maintained fleet of current-generation vehicles. Economy from 25-40 BGN ($14-22) per day — 20-30% below international brand rates. Good English-speaking staff. Cross-border permissions available for most EU destinations. Their website allows direct booking in English, and their customer service answers inquiries within a few hours. For budget-conscious travelers who want local pricing without sacrificing reliability, Top Rent a Car is the standard recommendation.
AutoUnion is another established Bulgarian agency with airport presence. Economy from 22-38 BGN ($12-21) per day. Older fleet on average, but good for budget-conscious travelers staying within Bulgaria. Check the vehicle condition at pickup more carefully with AutoUnion than with the international chains — not because the cars are unsafe, but because they have more mileage and pre-existing cosmetic wear.
Green Motion is an international-affiliated local brand with strong presence at SOF. Competitive with Top Rent a Car. Economy from 25-40 BGN ($14-22) per day. Their international affiliation means terms are more standardized than purely local operators.
Hertz Licensee: Some local operators at Sofia airport operate under international brand licenses. Verify which company is actually providing the car when booking through aggregators — the Hertz logo at the desk does not always mean Hertz’s own fleet.
Agency Comparison at Sofia Airport
| Agency | Economy (per day) | SUV (per day) | Automatic | Cross-border | Rating |

| AutoUnion | 22-38 BGN ($12-21) | 45-85 BGN ($25-47) | Limited | Ask | Average-Good |
Prices are approximate high-season daily rates for 7+ day rentals. Seasonal variation: low season (Nov-Mar) rates can be 30-40% lower.
Varna Airport (VAR) Car Rental
Varna Airport is 8 km from the city center, active year-round but significantly busier from June through September when charter flights from the UK, Germany, Poland, and Scandinavia fill the terminal. The arrivals hall shifts from quiet regional airport to organized chaos over the course of a Friday afternoon in July, as charters unload several hundred package holidaymakers simultaneously. Rental agency staff are well-practiced at processing this volume quickly, which is a good thing.
Summer premium: Rental rates at Varna increase 30-50% in July-August compared to shoulder season. This is real and significant. An economy car that costs 35 BGN/day in May can cost 60-80 BGN/day in August. This is not negotiable — the demand is genuine and there is no getting around it. Pre-book and accept the summer price, or adjust your travel dates.
Rental desk locations: All agencies have counters in the arrivals hall, clearly visible from the exit.
Operating hours: June-September: most agencies 06:00-midnight or later, given the volume of charter arrivals. October-May: reduced hours at local agencies, core agencies maintain reasonable coverage.
Agencies: Europcar, Sixt, Hertz, Budget, Avis, Top Rent a Car, and additional local operators have seasonal counters. Fleet availability is strong in summer (agencies bring additional vehicles from their national fleets), more limited in winter.
Economy rates: 35-55 BGN ($19-30) in shoulder season, 50-80 BGN ($28-44) in peak summer (July-August).
From Varna Airport to the City
The airport is 8 km south of Varna city center, connected by a well-maintained road. The drive takes 10-15 minutes. For the Black Sea coast driving, from the airport you can head directly south on the E87 toward Nessebar (100 km) without entering the city at all — useful if your accommodation is south of Varna.
Varna to the Black Sea Coast: Key Distances
| Destination | Distance from VAR | Drive Time | Notes |
|---|---|---|---|
| Varna city center | 8 km | 10-15 min | Via airport road north |
| Golden Sands (Zlatni Pyasatsi) | 15 km | 20 min | Major resort north of Varna |
| Albena | 25 km | 30 min | Resort complex, northwest |
| Balchik | 40 km | 45 min | Coastal town, Queen Marie’s palace |
| Nessebar (UNESCO) | 100 km | 1.5 hours | Old town on peninsula, south |
| Sunny Beach (Slanchev Bryag) | 110 km | 1.5 hours | Largest Bulgarian resort |
| Burgas Airport (BOJ) | 120 km | 1.5 hours | One-way drop-off route |
Burgas Airport (BOJ) Car Rental
Burgas Airport handles the southern Black Sea coast charter traffic — principally from UK, Germany, Poland, Czech Republic, and the Scandinavian countries. The airport is more seasonal than Sofia or even Varna, with most international activity concentrated June through September.
Summer premium: Higher than Varna due to the Sunny Beach proximity and high demand. Economy rates in July-August: 45-70 BGN ($25-39) per day.
Agencies: International brands (Europcar, Sixt, Budget) plus local operators (Top Rent a Car, AutoUnion) have seasonal counters. Pre-booking is important for summer arrivals — Burgas’ smaller fleet means popular categories sell out. Walk-in on a Saturday in July is not a strategy; it is a gamble with bad odds.
Economy rates: 30-50 BGN ($17-28) in shoulder season, 45-70 BGN ($25-39) in peak summer.
From Burgas Airport to the Coast: The airport is 11 km from Burgas city center and very well-positioned for the coast — Sunny Beach is 35 km north, Nessebar 30 km north, Sozopol 35 km south. From the airport, you can go directly to the coast without entering Burgas city at all, which saves time on arrival days.
Burgas to the Southern Coast: Key Distances
| Destination | Distance from BOJ | Drive Time | Notes |
|---|---|---|---|
| Burgas city center | 11 km | 15-20 min | Via main road |
| Nessebar (UNESCO) | 30 km | 35 min | Old town on peninsula |
| Sunny Beach | 35 km | 40 min | Largest Bulgarian resort |
| Sozopol | 35 km | 40 min | Ancient Greek colony, art galleries |
| Primorsko | 65 km | 1 hour | Smaller resort, less developed |
| Tsarevo | 80 km | 1.5 hours | Southern coast, near Turkish border |
| Varna Airport (VAR) | 120 km | 1.5 hours | One-way pickup/drop-off route |
Fuel Stations Near Sofia Airport
The most practical information for any airport pickup: where to buy the e-vignette and where to fill up immediately after renting.
| Station | Distance from T2 | Location | Notes |
|---|---|---|---|
| Lukoil Airport | 1 km | Airport road, terminal exit | Most convenient; sells vignettes |
| OMV Druzhba | 6 km | E871 ring road east | Good for heading toward Sofia |
| Shell Mladost | 8 km | Ring road, Mladost area | Full service, 24/7 |
| Petrol AD | 4 km | Airport access road | Local chain, competitive prices |
The standard procedure: Exit Terminal 2, get your car from the agency, drive to the Lukoil station at the airport road. Buy the e-vignette there (15 BGN / $8 for 7 days) using the license plate on the car. Fill up the tank if it was not given to you full. Now you are ready. This process adds 10-15 minutes and eliminates all the ways the morning can go wrong.
Airport Pickup Tips
Buy the e-vignette before your first motorway. You can purchase the electronic vignette online at bgtoll.bg (recommended — requires the car’s plate number, which you get at pickup), at the airport fuel station, or at border crossings. Without it, any motorway driving results in an automatic 300 BGN ($165) fine. Note: if buying online in advance, confirm the plate number with the agency before the rental — you cannot get this until you arrive at the counter. The practical solution is to buy it at the airport fuel station immediately after pickup.
At Sofia airport, use the fuel station vignette option. Since you need the plate number to buy online, the simplest approach at SOF is to complete the rental paperwork, get the car, then stop at the airport fuel station (just outside the terminal area) to buy the vignette with the actual plate number. Lukoil runs the station at the airport road exit and always stocks the 7-day vignette.
Cross-border is straightforward within the EU/Schengen. Bulgaria joined the Schengen Area (land borders) in January 2024, meaning driving to Romania and Greece is now border-free — no stop, no documents shown, no cross-border insurance needed for these EU neighbors. Serbia (border check), Turkey (border check and specific insurance required), and North Macedonia (border check) still require separate arrangements. Confirm cross-border permissions and documentation requirements with your agency before driving toward any non-EU border.
Photograph the car meticulously. Bulgarian rental cars may have more pre-existing minor damage than you are used to seeing in Western Europe — the country is larger and the roads more varied in quality. Do a systematic walk-around with close-up photos of every panel, all four tires, the undercarriage where visible, and the interior. At Burgas Airport in summer (charter flights, rushed turnover), agents can be under pressure to move quickly. Take your time regardless. An extra five minutes of photos is worth considerably more than discovering a “disputed” scratch at return.
Confirm the vignette status at pickup. Some Bulgarian agencies include a 7-day vignette in the rental rate. Others charge it separately (typically 15 BGN / $8). Clarify at the counter before driving off — the vignette question should be resolved before you reach the first motorway.
One-way rentals between airports. Sofia to Varna or Burgas one-way: typically 50-80 BGN ($28-44) drop-off fee. This makes practical sense for a coast-bound trip — fly into Sofia, pick up the car, drive the country, return the car at Burgas or Varna, fly home from the coast. Or vice versa. Confirm one-way availability and fee before booking.
Local SIM card at the airport. Vivacom, A1 Bulgaria, and Yettel have kiosks in arrivals areas. Tourist SIM with 5-10 GB of data: 10-20 BGN ($6-11). Essential for Waze (the preferred navigation app for locals, good for speed camera warnings in Bulgaria) and Google Maps.
Automatic transmission is scarce. Automatics are less common in Bulgarian rental fleets than in the US or UK. Economy and compact classes are predominantly manual. If you require an automatic, specify this at booking and confirm at pickup. Automatics command a premium of 10-15 BGN ($6-8) per day. In summer at Varna and Burgas, automatic economy cars can be sold out weeks before your arrival.
Common Airport Rental Traps
The vignette confusion. Some agents present the vignette as a mandatory extra charge without clarifying it should be included in the rental. Know in advance: a 7-day vignette is 15 BGN ($8). If the agent quotes 25+ BGN for the “mandatory” vignette, that is padding. Know the price before you arrive.
Insurance layering. Base rental includes TPL (third-party liability). CDW is often included in Bulgarian base rates (unlike some countries where it is always extra), but the excess can be high (200-500 BGN / $110-275). SCDW reduces the excess but adds 8-15 BGN/day. Know your credit card coverage before arriving and decide in advance. At the desk is not the moment to discover your card does not cover rentals in Bulgaria.
Summer coastal pricing. At Varna and Burgas in July-August, walk-in rates are significantly higher than pre-booked. Rental categories that are “available” at the counter are often only the higher-priced ones — the economy category sold out weeks ago. Pre-book at least 3-4 weeks ahead for summer coastal airports.
The fuel prepay offer. Some agents offer to prepay a full tank at a discounted rate and return the car empty. Bulgarian fuel stations are on every main road. Return the car full — it is always cheaper. Decline fuel prepay.
The navigation upsell. GPS rental: 15-25 BGN ($8-14) per day. Over a week: 105-175 BGN ($58-96). Waze works excellently throughout Bulgaria, including on the Rhodope mountain roads. Download offline Google Maps for Bulgaria before departure. Skip the GPS.
The emergency kit verification. Bulgarian law requires a warning triangle, reflective vest, fire extinguisher, and first aid kit in the vehicle. At rental pickup, verify all four are present — particularly the fire extinguisher, which is often the one missing and which is also the one you will regret not having if you need it. Ask the agent to confirm each item is in the car. If any are missing, request them before leaving.
One-Way Rentals
| Route | Drop-off Fee (approximate) | Availability |
|---|---|---|
| Sofia Airport to Sofia city | Free-10 BGN ($0-6) | Universally available |
| Sofia to Plovdiv | 20-40 BGN ($11-22) | Available |
| Sofia to Varna (airport or city) | 50-80 BGN ($28-44) | Available at major agencies |
| Sofia to Burgas (airport or city) | 50-80 BGN ($28-44) | Available at major agencies |
| Varna to Burgas (coast to coast) | 30-50 BGN ($17-28) | Available |
| Bulgaria to Greece | 80-200 BGN ($44-110) | Limited to agencies with partners |
| Bulgaria to Romania | 50-100 BGN ($28-55) | Limited |
The best one-way logic for Bulgaria: Fly into Sofia, pick up the car, drive the country (Sofia-Plovdiv-Rhodopes-Black Sea coast), drop off at Varna or Burgas, fly home from the coast. The one-way fee of 50-80 BGN is modest compared to the time and cost of driving 430 km back to Sofia. This is the standard circuit for visitors with a week to spend in Bulgaria.
Varna to Burgas one-way: If flying into Varna and out of Burgas (or vice versa), the 30-50 BGN drop-off fee covers the logistics nicely for a coastal tour that moves south (or north) rather than backtracking.
Pre-Booking vs Walk-In
| Scenario | Economy Car (7-day, Sofia airport) | Notes |
|---|---|---|
| Pre-booked online, 4+ weeks ahead | 175-280 BGN ($96-154) | Best rates, full choice |
| Pre-booked online, 1-2 weeks ahead | 245-350 BGN ($135-193) | Good rates, fewer options |
| Walk-in at Sofia airport | 280-420 BGN ($154-231) | Higher rates, decent choice year-round |
| Walk-in at Varna/Burgas (July-Aug) | 350-560 BGN ($193-308) | Significantly higher, limited availability |
Pre-booking saves 15-30% consistently at Sofia. At Varna and Burgas in summer, the gap is larger and availability is the bigger concern — walk-in in peak season may not find the category you want at any price.
Best booking platforms for Bulgaria: Discovercars covers local agencies (Top Rent a Car, AutoUnion) well. Localrent is less comprehensive in Bulgaria than in some Eastern European markets. Direct booking through Sixt.bg or Europcar.bg sometimes yields promotional rates or loyalty pricing. Compare both aggregators and direct before committing.
Airport Rental Strategy by Season
Bulgaria’s three-airport rental market behaves very differently depending on the time of year. Planning your booking strategy around this saves money and avoids the frustration of arriving at a summer coastal airport expecting choices.
| Airport | Jan-Apr | May-Jun | Jul-Aug | Sep-Oct | Nov-Dec |
|---|---|---|---|---|---|
| Sofia (SOF) | Good availability, low prices | Good, moderate prices | Busy but available | Good availability | Good availability |
| Varna (VAR) | Limited (low season) | Building up | Peak — book 4-6 weeks ahead | Declining but OK | Limited or closed |
| Burgas (BOJ) | Minimal presence | Seasonal ramp-up | Peak — book 4-6 weeks ahead | Sharp decline | Minimal or closed |
Sofia Airport: Year-Round Reliability
Sofia Airport is the only airport in Bulgaria where you can reliably walk up and rent a car in any month of the year. The fleet is larger, the competition between agencies is constant, and the prices are the most stable. For visitors arriving via Sofia regardless of final destination, picking up at SOF is almost always the right decision.
Tips specific to Sofia Airport:
The e-vignette question comes up at every SOF rental counter. Some agencies include a 7-day vignette (15 BGN) in the rate; others add it separately; others leave it to you. Clarify this before driving off. The airport fuel station (Lukoil, just outside Terminal 2) sells vignettes if you need to buy one after pickup.
The drive from Terminal 2 onto the E871 ring road is well-signed. The junction that sends you toward the A1 motorway to Plovdiv/Burgas is 8 km from the terminal — this is where the vignette would first be checked, so buy it before this point.
Varna and Burgas: Summer-Only Planning
At Varna and Burgas airports in July-August, walk-in availability is genuinely uncertain. Popular categories (compact, any automatic) often sell out by mid-morning on peak arrival days. Pre-booking at these airports in peak summer is not optional — it is the only way to guarantee a car.
At Varna Airport, the arrivals area empties quickly as charter passengers collect bags and head to their coaches. The rental queue moves fast because the agencies are experienced at processing groups. However, if your category is unavailable, options for substitution are limited because there may not be another car in the lot.
At Burgas Airport, the situation is more acute because the airport is smaller, the summer fleet is brought in seasonally, and the agencies are less staffed than at Varna. Arrive with a pre-booking, the car’s specific details confirmed, and your credit card limit adequate for the deposit.
Deposit at summer coastal airports: Summer deposits at Varna and Burgas can be higher than at Sofia due to the increased risk of undisclosed damage from rapid summer turnover. Typical deposits: economy class 200-400 BGN ($110-220) with SCDW included, 500-800 BGN ($275-440) without. Make sure your card has this headroom on arrival.
Vehicle Selection Guide for Bulgarian Roads
Not all cars handle Bulgaria’s road variety equally. Choosing the right vehicle for your itinerary avoids frustrating limitations.
| Itinerary Type | Minimum Recommended | Notes |
|---|---|---|
| Sofia city only | Economy | Parking easier in smaller cars |
| Motorway touring (A1, A3) | Economy | Motorways are excellent |
| Rila Monastery day trip | Economy/Compact | Road is paved but has curves |
| Black Sea coast | Economy | E87 road is straightforward |
| Rhodope mountains | Compact/Crossover | Some rough secondary roads |
| Pirin off-road (Melnik area) | Crossover/SUV | Sand track to Melnik pyramids |
| Remote Rhodope (Trigrad) | Crossover | Gorge road is rough in sections |
| Winter mountain driving | SUV with snow tires | Essential November-March |
The most common mistake is booking an economy car for a trip that includes substantial Rhodope mountain driving. The roads are passable but the underbody clearance and suspension on the smallest economy cars is strained by sustained rough secondary roads. A compact or crossover gives meaningfully more comfort without a dramatic price increase — typically 10-15 BGN ($6-8) per day more, which over a week adds 70-105 BGN ($39-58) to the total. Against a week of Rhodope driving comfort, that math is easy.
Winter vehicle requirements: From November 15 to March 1, Bulgarian law requires winter tires. Rental agencies should fit them automatically during this period — confirm at pickup rather than assuming. If you are renting during the shoulder (early November, early March), ask explicitly about tire type.
Post-Pickup Route Planning
From Sofia Airport, the first routing decision depends on your initial destination:
Toward Sofia city center: Take the E871 ring road west, then follow signs for Centrum (15-25 min). The ring road connects to all main city arteries. Use Waze for rush-hour routing — the ring road has congestion management issues in the mornings.
Toward Plovdiv/Rila/Bansko: Head south on the ring road to the A3/A1 junction. Vignette needed from this point. Plovdiv is 145 km (1.5 hours) on A1 Trakiya. Rila Monastery is 117 km south (about 2 hours via the A3 and E79).
Toward Varna/Black Sea (A2): Head east on the ring road to the A2 junction (Sofia-Varna highway). Some sections of A2 are still on the old road alignment — GPS or Waze will route you correctly, routing around the incomplete sections.
Toward northern Bulgaria: Head north on the E79 toward Montana/Vidin. No motorway for most of this route — good quality E-road. The Belogradchik rocks area (a remarkable natural formation) is 180 km from the airport, about 2.5 hours.
Toward Bansko and the Pirin: Take the A3 (Struma motorway) south toward Blagoevgrad, then secondary roads east toward Bansko. Total 160 km, about 2 hours. Bansko is Bulgaria’s most developed ski resort and a good base for the Pirin region.
