The Slovenian coast and the Karst, the Obalno-kraška region

The 47 km coast: Piran, Izola, Koper and Ankaran

The coast is shared between Ankaran, Koper, Izola and Piran, all four with official Slovene and Italian names. Piran is the one on the postcards, with Tartini Square, named after the violinist Giuseppe Tartini who was born there, the Venetian house of the «Lassa pur dir» legend and St George’s Cathedral above the old town. The municipality had 631,821 arrivals in 2025, second only to Ljubljana, and includes Portorož, Strunjan and the Sečovlje salt pans, founded in 804.

Koper is the real town, with 26,579 people, the country’s main port and an old centre built around Tito Square, the Praetorian Palace and a 54 m bell tower from the 12th century. Izola is the fishing town, with eight beaches in 5 km, and Ankaran, the smallest at 8.1 km² and a single settlement, opens the coast with the Debeli rtič park.

How to split your days

With five days I would give two to the coast and three to the Karst. On the coast, one day for Piran and the salt pans and one for Koper, Izola and Strunjan. In the Karst, one day for Škocjan and Lipica, one for Štanjel and the wineries, and one for inland Istria, with Hrastovlje and its Dance of the Dead. Short on time, keep Piran and Škocjan, and save the rest for a second, longer visit.

What the Karst has that the coast lacks

Geologists everywhere borrowed the word karst from the Karst, and climbing up from the sea you quickly understand why. Rivers vanish underground, sinkholes pit the fields, villages are built of stone and the bora wind shapes both the landscape and the ham. The Škocjan Caves, in Divača, have been on the World Heritage List since 1986 and UNESCO describes them as an underground canyon of exceptional size, cut by a river. Vilenica Cave, in Sežana, is close by.

At Lipica, in the municipality of Sežana, the stud farm founded in 1580 is the birthplace of the Lipizzaner, with more than 300 horses, a museum and a classical riding school. And in Komen municipality, Štanjel is a medieval stone village with a castle, where the architect Maks Fabiani left his mark.

The hinterland most people drive past

Between the coast and the Karst lies a strip that most visitors cross on the motorway without stopping, which is a shame. The Karst edge above Koper, Kraški rob, is a climbing area with more than 800 routes, the Osp wall being the best known. Inland from Piran, Padna is a protected Istrian hamlet, and the Dragonja valley and the Šavrin hills are olive country, with farms such as Gramona pressing their own oil. In Koper’s hinterland, the pentagonal tower at Kubed has a giants’ trail and Marezige a wine and olive oil fountain.

Further east, Hrpelje-Kozina leads into Brkini, terraced orchard hills known for plum dumplings and plum brandy. It is the Slovenia I would look for to eat well away from the crowds, and it gets its own page, Slovenian Istria.

Food and wine

On the coast it is fish, with Piran sea bass baked in salt and Izola’s brodet. In the Karst, teran, the red wine of the red earth, bora-cured pršut and cheese. Slovenian Istria makes malvazija and refošk, and the tourist board says Slovenia’s biggest wine barrel belongs to Vinakoper.

Getting there and around

The region sits between Trieste and Istria. The tourist board mentions an Arriva bus linking Koper with Trieste every day except Sunday and, in summer, plenty of coaches from Ljubljana down to the sea. For the Karst, with its small villages and scattered caves, a car saves a great deal of time. On motorways you will need DARS’s electronic vignette, compulsory for vehicles up to 3,500 kg.
