Dobrna, six centuries of spa life below Paški Kozjak

A spa village near Celje

According to SURS, Dobrna has 580 residents and its municipality 2,347 on 1 January 2026, spread over 11 settlements. Over the year before, it logged 21,186 arrivals and 115,386 overnight stays, more than five nights per visitor. The tourist board places it about 16 km north of Celje, 13 km from Velenje and 28 km from Laško, and Dobrna holds the bronze level of the Slovenia Green Destination scheme. The spa also holds the EU Ecolabel.

Slovenia’s oldest working spa

The Celts and Romans already knew its warm springs, but the date that counts is 1403, when the water began to be used for healing, as it still is. That’s why the tourist board presents Terme Dobrna as Slovenia’s oldest spa in operation, with more than 610 years behind it. In 1814 the estate passed to Baron Kajetan Dienersberg, and in the early 20th century the spa was famous for its guests, among them the writer Karl May in 1907.

Today it has thermal pools, saunas, a massage and beauty centre and a diagnostics and rehabilitation centre. Children have a mini club with workshops, so parents can take their treatments in peace.

The park and the surroundings

The spa park is linked to the centre by an avenue of chestnut trees more than 200 years old, and it’s home to a white poplar that’s the third-thickest known of its species in Slovenia. In the Valley of Mills, by the Temnjaški vrelec stream, a mill about 450 years old still works, near the ruins of Snake Castle. The Šumej homestead at Brdce keeps a black kitchen that shows how people lived three hundred years ago, and collector Jože Polenek displays around 10,000 old objects in a three-storey house.

Walking, cycling and eating

Ana’s Trail passes the Šumej homestead and includes a forest section from the Ledenica cave, where there’s a Kneipp spring. The Loka trail leads to Snake Castle and the Valley of Mills. There are five cycle routes and bikes for hire. At the table, the Arnika Dobrna women’s association cooks from their grandmothers’ recipes, and walnut bread is the speciality. On Saturday 7 November 2026 the village celebrates St Martin’s Day with the christening of the new wine, according to the municipality.

Fitting it in

I’d come for at least three nights, to mix the water with unhurried walks. If you’re comparing spas in Slovenia, Dobrna is one of the quietest.
