The Karst, the stone plateau that gave its name to every karst in the world

The plateau that gave karst its name

The Karst, Kras in Slovene, is the limestone plateau stretching between the Gulf of Trieste, the Vipava valley and the Brkini hills, and it carries on partly into Italy. Here water met a soluble rock and together they made a world of caves, sinking rivers and sinkholes. The word comes from an old term for stone, and the Slovene Wikipedia records the form Grast as early as 1177. The German Karst and the Italian carso came from the Slovene, and with them the scientific name for such landscapes everywhere.

The most visible feature is not underground. It is the dry stone walls dividing meadows and pastures, the small quarries every village had, known here as jave, and a stonemasons’ tradition going back to antiquity that shows in doorways, steps, well heads and the arched gateways into the farmhouses, the kalone.

Škocjan and the Karst caves

The Karst’s most dramatic side is below ground. The Škocjan Caves, in the municipality of Divača, have been a World Heritage Site since 1986. There the river Reka has cut an underground canyon whose halls reach 150 m in height, and a 2026 visit costs €16 to €24 depending on the month. Vilenica Cave, near Lokev, has been visited since 1633 and its website calls it the world’s first show cave. There are others, such as Divača Cave, which drew visitors in the 19th century.

Teran and Karst ham

The red soil, the terra rossa, colours the landscape and flavours everything that grows in it. The Karst tourist board sums it up as Teran, the plateau’s pleasantly tart red, ham cured on the farms, a cheese of its own, herbs from the Karst heath and honey. Brkini, on the edge, adds fruit, with its plum brandy, which holds a protected geographical indication just like the Karst juniper brandy.

Many farms open their cellars and tables to visitors. My advice is to stop at one at lunchtime, between caves, and order ham and Teran.

Lipica, Štanjel and the stone villages

In Lipica, which belongs to Sežana, Lipizzaner horses have been bred since 1580; they are born dark and turn white with age. The stud has more than 300 horses, and the tourist board calls it the largest Lipizzaner stud in the world.

Štanjel is the finest Karst village, with narrow streets built against the bora, stone houses round enclosed courtyards, a restored castle and the garden designed by Maks Fabiani. It holds its wine festival from 5 to 8 November 2026. For the rest of the region, coast included, start with the coast and the Karst, the region as a whole. If you can choose your dates, autumn in Slovenia is the ideal season for the plateau, with St Martin’s Day and the new wine in November.
