Every Country on My Balkans Road Trip, Ranked: Croatia vs Slovenia vs Bosnia vs Serbia vs Romania vs Hungary vs Bulgaria

We did a 15-day, roughly 3,400-mile loop through the Balkans in August 2022: three of us, one rental car, one long circle starting and ending in Bucharest. Seven countries with a real border crossing (plus a day trip into an eighth). If you’re trying to figure out which Balkan countries are worth your limited days, here’s the ranking, based on what actually held up on the ground.

The ranking, short version:

1. Croatia: the coastline is why most people start this trip, and it delivers; the national parks are why you should give it more days than we did.
2. Slovenia: small enough to loop in a single day, and the day was packed with variety.
3. Bosnia & Herzegovina: the cheapest, and the most different from anywhere else on the route.
4. Montenegro: only saw it as a day trip from Dubrovnik, but the Bay of Kotor earns its reputation.
5. Hungary: Budapest is a great city, but it’s a city stop, not the reason to do this whole loop.
6. Serbia: a solid, underrated stopover, less polished than Croatia and cheaper for it.
7. Romania: home base for us (we flew in and out of Bucharest), so it’s ranked lower here only because we know it well and it’s not the novelty of the trip, not because it’s less worth visiting.
8. Bulgaria: we only had one night in Sofia, which isn’t enough to rank it fairly, but it’s here for completeness.

Quick comparison table

Country	Days spent	Avg cost feel	Best for	Skip if
Croatia	4 nights (Split + Dubrovnik) + transit days through Plitvice/Krka	Mid-to-high (tourist pricing on the coast)	Coastline, national parks, photogenic road stops	You’ve already done a dedicated Croatia trip
Slovenia	2 nights in Ljubljana, one full day looping the countryside	Mid, noticeably cheaper than coastal Croatia	Packing a lot of variety (gorge, lake, cave, castle, coast) into one day	You only have time for cities, not day-tripping by car
Bosnia & Herzegovina	1 night in Sarajevo, passed through Mostar	Low — cheapest stop on the trip	Budget travelers, a genuinely different pace and history than the EU side	You’re not comfortable with more visible war history and a rougher-around-the-edges vibe
Montenegro	Day trip only (from Dubrovnik)	N/A — didn’t stay overnight	A scenic detour if you’re already in Dubrovnik	You don’t have a spare day near Dubrovnik
Hungary	2 nights in Budapest	Mid	A big city with real nightlife and architecture as a loop anchor	You’d rather spend those 2 nights on the coast
Serbia	2 nights in Belgrade	Low-to-mid	Cheaper stopover between Bosnia and Bulgaria, less touristy	You’re tight on days and have to cut somewhere in the middle of the loop
Romania	3 nights total in Bucharest (start/end) + a day trip into the mountains	Low-to-mid	Bookending the trip, castle day trip logistics	You’re not flying in/out of Bucharest
Bulgaria	1 night in Sofia	Low	A quick stopover on the way back to Romania	You want more than a single night to judge a whole country

Avg cost feel is directional, based on our lodging/meals impressions in 2022, not a formal per-country budget breakdown (we tracked total trip costs, not itemized by country).

1. Croatia — the coastline justifies the hype on its own

Croatia was the section of the trip built around two national parks and two coastal bases. Our route through Croatia ran Zadar → Split (2 nights, $315 for the group) → Dubrovnik (2 nights, $291), with the drive from Ljubljana routed through Plitvice Lakes and then Krka waterfalls on the way to Split. Our itinerary was built around hitting both parks on that drive day, and here’s the honest version: we made brief stops at both, but didn’t hike either one. The day was too itinerary-dense for trails or a real park visit — the parks became a look-and-drive-on rather than a destination. If the waterfalls are a priority for you, that’s the single biggest change I’d make to this loop — give the Ljubljana-to-Split leg two days instead of one, because the driving day as we built it doesn’t leave room for a real park visit.

What I can say first-hand: the coastal drive between Zadar and Split, and again down to Dubrovnik, is one of the best stretches of driving on the whole loop. Most of it hugs the Adriatic. The beaches down here are rocky, not sand, so water shoes aren’t optional if you actually want to get in the water, and you’ll want towels for both the beach and your car seats, because they get scorching hot sitting in the sun. Dubrovnik’s Old Town is dense and walkable, and it’s also the base for the Montenegro day trip (more on that below).

Split and Dubrovnik both ran noticeably higher than our other lodging costs on the trip. This was the most expensive coastal stretch of the 15 days. We’ve also ranked our favorite beach destinations if coastline is your main draw.

2. Slovenia — small country, absurdly efficient day trip

Ljubljana was a 2-night stop ($260 total), and the value of Slovenia on this route isn’t really the city: it’s that you can build one enormous loop day out of the countryside around it. Our planned loop for that day covered Vintgar Gorge, Lake Bled, Postojna Cave, Predjama Castle, and Piran, and we made four of the five: Lake Bled, Postojna Cave, Predjama Castle, and Piran. Vintgar Gorge was the stop that fell off — the first casualty of an ambitious list, and honestly the right one to cut, since Bled covers the alpine-scenery slot on its own. Lake, cave, cliffside castle, and a coastal town in one driving day is already an absurd range for one small country, and it’s the single best day-trip argument for putting Slovenia on this loop.

Slovenia felt cheaper than the Croatian coast for lodging and food, and the drive from Ljubljana into Croatia (toward Plitvice) was about 4 hours, which is a reasonable travel day if you’re also sightseeing along the way.

3. Bosnia & Herzegovina — cheapest, and the most different

One night in Sarajevo ($97 total for the group), reached via a 2-hour drive that routes through Mostar. This was the cheapest overnight of the entire trip by a wide margin, and the border crossing into Bosnia is also where the trip stops feeling like the EU. Bosnia is not in the Schengen zone, so expect an actual passport check, not a highway sign you drive past.

I’ll be straightforward about the limits of what I can vouch for here: one night in Sarajevo, after a full day of driving with a stop in Mostar, is a short visit. What stood out is how different the built environment and history feel here compared to Croatia or Slovenia just a couple hours away: it’s a genuinely different country, not a cheaper version of its neighbors. If your budget is tight, this is the stretch of the trip where your money goes the furthest.

4. Montenegro — day trip only, but earns its spot

We didn’t stay overnight in Montenegro. This was a day trip to the Bay of Kotor from our Dubrovnik base. We drove the bay road and walked Old Town Kotor, and that combination is exactly why it ranks this high: the drive around the bay is the dramatic part (the road hugs the water most of the way around, with the mountains dropping straight into it), and the walled Old Town at the end of it gives the day a destination instead of just a scenic loop. A full day dedicated to one specific place delivered a clearer, more concentrated impression than any single day we spent in a capital city on this trip.

If you’re already staying in Dubrovnik, this is an easy add without needing another hotel night.

5. Hungary — a great city, but a city, not a loop highlight

Budapest was our first stop after Bucharest (2 nights, $300 total), after a genuinely long 10-hour drive from Bucharest. That drive is the longest single leg of the whole trip, so budget your first day accordingly; it’s not a light after-work kind of drive.

Budapest itself is a strong city stop, ranked here lower than the more nature-driven and novel stretches of the trip only because a big European capital is something you could visit on its own, disconnected from a Balkans road trip, and get the same experience. It’s worth 2 nights, but it’s not the differentiator that makes this specific loop worth doing.

6. Serbia — underrated, less polished, cheaper

Belgrade got 2 nights ($210), reached via a 5-hour drive from Sarajevo. Serbia doesn’t get the marketing that Croatia or Slovenia get, and the lodging cost reflected that, noticeably cheaper than the coastal stops. This is the stretch of the trip where I’d tell someone doing a similar loop to lower their expectations of polish and raise their expectations of value; it’s a solid stopover, not a detour.

7. Romania — home base, not a novelty for us

Romania bookended the trip: 1 night in Bucharest at the start ($121) and 2 nights at the end ($154), plus a day trip into the mountains that made it to Snagov, the Peles and Pelisor castles at Sinaia, Rasnov, and Bran Castle — about 6.5 hours of driving for that loop. Brasov was on the plan and was the stop we cut; by the time we’d done the castles, adding a proper old-town walk would have pushed the drive back to Bucharest past reasonable. If you want Brasov, make this an overnight instead of a day loop.

Romania ranks lower here specifically because it’s where we started and ended: familiar ground for us, not the part of the trip that felt new. If you’re not flying in and out of Bucharest, your version of this loop probably treats Romania differently, maybe as more of a highlight than a bookend.

8. Bulgaria — one night isn’t enough to really rank it

Sofia got a single night ($71), on the drive back from Belgrade to Bucharest, a 5-hour leg that we split with a mention of Veliko Tarnovo as a routing point. One night in a capital city after a full driving day is genuinely not enough to form a real opinion, so I’m ranking Bulgaria last here mostly by default. If you have the flexibility, giving Sofia 2 nights instead of 1 seems like the obvious fix to this loop if we did it again. More on how we book stays now: what I’d do differently about accommodation.

Practical logistics

Rental car: $1,416.95 total for 15 days, split three ways ($472 per person). That’s for one car across the whole loop, with no one-way drop fees since it was a closed loop back to Bucharest.

Gas: we estimated around $550 total for roughly 3,400 miles at 2022 EU fuel prices (~$200 per person). Fuel prices across the EU have moved since 2022; budget for that estimate to be low today rather than treating it as current.

International Driving Permit: we got ours through AAA before the trip, and needed it. As of 2026, research into current requirements suggests the rules are similar to what we experienced: most Western licenses are accepted in Croatia, Bosnia, and Montenegro, but an IDP is still recommended (and in some cases required) for Serbia, Bosnia, and Montenegro specifically, and it’s cheap insurance regardless (Balkan Guide, 2026; Montenegro Car Hire border guide, 2026).

Border crossings: this route crosses in and out of the Schengen zone multiple times. Slovenia, Croatia, Bulgaria, and Romania are all Schengen, while Bosnia, Montenegro, and Serbia are not. That means real passport checks at some crossings, not a drive-through. As of 2026, research indicates the EU rolled out its Entry/Exit System (EES) at Croatian borders in April 2026, adding biometric registration for non-EU/EEA travelers on their first crossing, so expect that to add wait time at Croatia’s borders that we didn’t experience in 2022 (Secret Dalmatia Blog, 2026; easybalkantransfers.com, 2026). Busier crossings like Croatia-Serbia and Croatia-Bosnia can reportedly see 30-90 minute queues in summer, so build slack into your drive days around those legs.

Lodging: all Airbnbs, all booked in advance, totaling $1,820 for the group across 15 nights (about $606 per person, or roughly $40/night per person). Parking was free at almost every stop, which isn’t something I’d assume holds everywhere in Europe.

The 4am problem: our flight home required a 4am car return ahead of a 7am flight out of Bucharest. If your loop ends the same way (flying out early from wherever you return the car), build in a buffer night near the airport rather than trying to drive in that morning.

All-in cost: across flights (Delta, $798.26 per person including $167 of travel insurance), lodging, rental car, and gas, we landed around $2,076 per person for the full 15 days. That’s a real, tracked number from our trip in 2022; expect meaningfully higher flight and gas costs booking this same loop today.

FAQ

Is Croatia or Slovenia better for a Balkans trip?

They do different jobs. Croatia is the coastline-and-national-parks stretch: plan more days there if beach time and Plitvice/Krka are the priority. Slovenia is small enough to cover in a single big day loop out of Ljubljana and hits gorge, lake, cave, castle, and coastal town variety in that one day. If you can only pick one, it comes down to whether you want days of coastline (Croatia) or one dense, efficient day of variety (Slovenia).

How many days do you need for a Balkans road trip?

We did 15 days and 3,400 miles across 7 countries plus a day trip into an 8th, and it felt full but not rushed for a first-timer’s loop touching every country briefly. If you want more than a taste of any single country (especially Croatia’s coast), you’d want closer to 3 weeks, or narrow the loop to fewer countries.

Is driving in the Balkans safe?

We didn’t have any safety incidents on the roads across the 15 days. The bigger practical issues were the length of some drive legs (the Bucharest-to-Budapest leg alone was 10 hours) and border-crossing wait times rather than road safety itself. An International Driving Permit is worth getting regardless of strict necessity.

Do you need an International Driving Permit for a Balkans road trip?

We got one through AAA before the trip and used it. Research into 2026 requirements suggests it’s still recommended, and sometimes required, particularly for Serbia, Bosnia, and Montenegro, so get one before you go rather than finding out at a rental counter.

What’s the cheapest country to visit on a Balkans loop?

Bosnia & Herzegovina was the cheapest overnight of our entire trip ($97 for one night in Sarajevo for three people), and Serbia and Bulgaria also ran noticeably cheaper than the Croatian coast or Budapest.
