Slovenia
Slovenia is almost perfectly sized for a road trip. The country is roughly the size of Wales, but it packs in an extraordinary range of landscapes — alpine peaks, karst plateaus, vineyard-covered hills, and a short but scenic Adriatic coastline — all within a few hours of each other. The roads are good, the distances are manageable, and the country has none of the traffic or congestion that makes driving in larger European destinations frustrating.
A straightforward loop from Ljubljana takes in Lake Bled and the Bohinj valley in the northwest, the Soča river valley with its impossibly turquoise water, the Karst region and the caves at Postojna, and the coastal town of Piran — all within five or six days of easy driving. The Julian Alps in the northwest are the most dramatic part of the country, and the scenery along the Vršič Pass, the highest mountain pass in Slovenia, is genuinely breathtaking. The area is also a wonderful base for walking, and many visitors combine their road trip with Slovenia hiking tours that explore the Julian Alps on foot over several days.
“Slovenia rewards the driver who takes the smaller road. The main routes are fine, but the back roads are where the country really opens up.”
Portugal
Portugal is long and narrow, which makes it naturally suited to a north-to-south road trip. The country divides neatly into distinct regions — the green, rainy Minho in the far north, the dramatic Douro Valley wine country, the vast open plains of the Alentejo, and the sun-bleached cliffs of the Algarve in the south — each with its own food, architecture, and pace of life. Driving between them takes time but never feels like a chore, because the landscape changes consistently enough to hold your attention throughout.
The Douro Valley deserves particular mention. The road that follows the river east from Porto through terraced vineyards to the Spanish border is one of the finest drives in southern Europe, and the small quintas along the way offer wine tastings and accommodation that make it easy to slow the whole trip down to a very pleasant crawl.
Estonia
Estonia is one of the least visited countries in the European Union and one of the most rewarding for a self-drive trip. The country is flat, forested, and quietly beautiful — a landscape of birch woods, bog trails, and small wooden farmhouses that feels entirely unlike anywhere else in Europe. The roads are empty by western European standards, and the distances between places are short enough that you rarely feel like you’re just driving to get somewhere.
Tallinn’s medieval old town makes a natural starting point, but the most memorable parts of an Estonian road trip tend to be further afield — the islands of Saaremaa and Hiiumaa, reached by short ferry crossings, the coastal cliffs at Ontika, and the eerie Soviet-era infrastructure that appears unexpectedly in otherwise rural landscapes. It is a country that takes a little more curiosity than most, and rewards it in kind.
Montenegro
Montenegro is tiny — smaller than Connecticut — but its landscapes are wildly varied and its roads are among the most dramatic in Europe. The drive from the Adriatic coast up into the mountains takes less than an hour but feels like crossing between entirely different worlds. The Bay of Kotor, a winding inland sea flanked by steep limestone mountains, is one of the most striking stretches of coastline in the Mediterranean, and the road that loops around it is best driven slowly, stopping often.
Further inland, the Durmitor National Park offers high-altitude scenery that rivals anything in the western Alps, with deep glacial lakes and a canyon carved by the Tara River that is among the deepest in Europe. Montenegro is still relatively undiscovered by mass tourism, which means the roads are quiet, the prices are reasonable, and the experience feels genuinely off the beaten track in a way that’s increasingly hard to find in Europe.
