Route Overview
The Route South
The drive from Budapest to the Croatian coast follows one of the most well-travelled holiday routes in Central Europe. Every summer, thousands of Hungarian families load up their cars and head south on the M7 motorway toward the Adriatic. The route is straightforward, the roads are good, and the distance is manageable in a single day with a couple of stops.
From Budapest, the M7 motorway runs southwest past Lake Balaton to the Croatian border near Letenye. This first section takes about two and a half hours. After crossing into Croatia, you join the A4 motorway toward Zagreb, and from there the A1 motorway heads south toward the coast. The entire drive from Budapest to Split is approximately 650 kilometres and takes about seven hours with stops.
The alternative, and in my view better, approach is to leave the motorway after Zagreb and take the old road through the mountains to the coast, stopping at Plitvice Lakes National Park on the way. This adds about two hours to the journey but includes one of the most spectacular natural sights in southern Europe.
Crossing the Border
Since Croatia joined the Schengen Area in January 2023, border controls between Hungary and Croatia have largely been removed. In practice, you may still encounter occasional spot checks, particularly during summer weekends, but these rarely cause significant delays.
The main border crossing is at Letenye (Hungarian side) / Goricani (Croatian side) on the M7/A4 motorway. There is also a crossing at Barcs further east, which can be useful if you are coming from eastern Hungary or if the main crossing has unusual queues.
Keep your passport or EU ID card accessible. Vehicle registration documents and valid insurance green card should be in the car, though they are rarely checked at Schengen borders.
Hungarian Section: Budapest to Letenye
The M7 motorway from Budapest runs past the eastern end of Lake Balaton and continues southwest through the gently rolling countryside of Zala County. This stretch is 230 kilometres and takes about 2.5 hours.
The road is dual carriageway throughout with good surfaces and regular service areas. The MOL station at the Balatonvilagos exit is a good stop for fuel and food, roughly 90 minutes from Budapest. After that, service areas become less frequent in Zala County.
Fill up before crossing the border. Hungarian fuel prices are still noticeably lower than Croatian prices, sometimes by 15 to 20 percent.
Croatian Section: The Motorway Route
After the border, the A4 motorway leads you to Zagreb in about 90 minutes. You skirt the northern edge of the Croatian capital and join the A1 motorway heading south toward Karlovac and the coast.
Croatian motorways are toll roads with physical toll booths. You collect a ticket when you enter the motorway and pay when you exit. The toll from Zagreb to Split is approximately 25 EUR for a standard car. Both credit cards and cash (kuna or euros) are accepted at toll booths.
The A1 between Zagreb and Split is one of the most impressive pieces of road engineering in the Balkans, cutting through the Dinaric Alps with a series of tunnels and viaducts. The Sveti Rok tunnel (5.6 km) is the longest and marks the transition from the continental climate to the Mediterranean. When you emerge from the tunnel on the southern side, the landscape changes dramatically, from forested mountains to dry karst and eventually the sea.
The Plitvice Lakes Detour
Plitvice Lakes National Park is about 130 kilometres south of Zagreb, just off the old road to the coast (Route D1). If you leave the A1 motorway at Karlovac and follow the D1 instead, you pass directly through the park.
The park consists of 16 interconnected lakes arranged in terraces, connected by waterfalls that cascade over travertine barriers. The colour of the water, a deep turquoise that shifts depending on the mineral content and the angle of the light, is unlike anything I have seen elsewhere in Europe.
There are two main entrances: Entrance 1 (Rastovaca) for the lower lakes and Entrance 2 (Flora) for the upper lakes. The lower lakes are more dramatic and include the largest waterfall, Veliki Slap (78 metres). The upper lakes are quieter and connected by wooden boardwalks over the water.
A visit to both sections takes 4 to 6 hours. Entry tickets cost 30 EUR in summer (July-August) and 20 EUR in shoulder season. The park can be very crowded in July and August, and I would strongly recommend visiting in May, June or September when the water levels are good and the crowds manageable.
Reaching the Coast
From Plitvice, the D1 continues south through the mountains to the coast at Zadar (about 130 km, 2 hours) or you can rejoin the A1 motorway at the Gornja Ploca interchange and continue to Split.
Zadar is my preferred coastal destination from this route. It is smaller and less overwhelming than Split, with a well-preserved old town built on a peninsula, Roman ruins, and the Sea Organ, an experimental musical instrument built into the waterfront steps that is played by the waves. The sunset from Zadar's waterfront was famously described by Alfred Hitchcock as the finest in the world.
Split is the larger city and the gateway to the Dalmatian islands. The old town is built within and around the walls of the Roman Emperor Diocletian's Palace, which gives it a layered, lived-in quality that is quite different from most Mediterranean old towns. Parking in Split's old town area is extremely limited. Use the Sukoisan or Znjan car parks and walk or take a bus.
The Istrian Alternative
If you prefer a shorter drive and a different kind of coastline, consider heading to Istria instead of Dalmatia. From Zagreb, the A3 motorway runs west to the Istrian peninsula in about two and a half hours.
Istria has a more Italian feel than the Dalmatian coast, with hilltop villages, truffle hunting, excellent wine, and a coastline that ranges from pebble beaches to the old Venetian port towns of Rovinj and Porec. The food in Istria is arguably the best in Croatia, blending Italian and Central European traditions.

Practical Details
- Documents: Passport or EU ID card, vehicle registration, insurance green card, and driving licence.
- Fuel: Fill up in Hungary before the border. Croatian fuel prices are 15-20% higher. Shell and INA are the main chains in Croatia.
- Speed limits: 130 km/h on Croatian motorways, 90 km/h on main roads, 50 km/h in towns. Speed cameras are common, particularly on the A1 near Split.
- Toll costs: Expect to pay approximately 25-35 EUR in Croatian tolls depending on your destination. Keep some cash for smaller toll booths.
- Emergency: European emergency number 112 works in all countries along the route. Croatian roadside assistance is available on 1987.
- Return route: Consider returning via a different route. The coastal road (Jadranska Magistrala) from Split to Rijeka is one of the most scenic drives in Europe, though it is slow and winding.
Summer weekends in July and August see the heaviest traffic on the A1 south of Zagreb, particularly on Friday afternoons (southbound) and Sunday afternoons (northbound). If possible, time your travel to avoid these peaks. Early morning departures typically avoid the worst congestion.
