Idrija Mercury Mine
The Idrija Mercury Mine is one of the world's largest mercury mines and a UNESCO World Heritage site (inscribed 2012). Anthony's Shaft, dug in 1500, is the oldest preserved mine entrance in Europe. The mine's 500-year operation shaped Idrija's economy, drove lace-making as supplementary income for mining families, and left a material layer visible in the town's architecture and landscape.

Lake Cerknica
Lake Cerknica is the largest intermittent lake in Slovenia and one of the largest in Europe—its surface can reach up to 38 km² and its mysterious disappearing and reappearing cycle directly shapes the cultural calendar of the Cerknica plain. The Jezernik (Lake Man) myth explains the lake's disappearance, and the drevak boat tradition encodes the seasonal rhythm of flooding (~260 days/year). Valvasor documented the lake in 1689, making it one of the earliest recorded karst phenomena.

Walk the lakebed when dry, observe the intermittent flooding cycle, take a drevak boat ride during high water, and visit the Museum of Lake Cerknica.
Predjama Castle
Predjama Castle is perched 123 meters up a steep overhanging cliff in a cave—one of the world's most dramatic castle settings. The legend of Erasmus of Lueg, the 'Slovenian Robin Hood' who survived siege via a secret tunnel through the cave, embodies Habsburg-era frontier rebellion. The cave behind the castle spans four floors and connects to the second-longest Slovenian cave system.

Climb to the castle perched 123 meters up a cliff, explore the cave behind it, learn about Erasmus of Lueg's legendary siege, and see the secret tunnel that kept him supplied.
Slivnica
Slivnica is the mythological center of the Cerknica Carnival—Valvasor documented the folk belief that witches brew storms on its peak, and the mountain overlooks Lake Cerknica and the Notranjska valleys. The witches Uršula and Liza remain central carnival figures, making Slivnica a living ritual anchor where folklore and carnival practice converge. The hike to the summit reveals the same panoramic vista that inspired Valvasor's 1689 account. Anchor modes: living_ritual; material_layer | Search hooks: Slivnica; Mount Slivnica; witches of Slivnica; Coprnice Uršula; Cerknica valley overlook
Hike to the summit for panoramic views of Lake Cerknica and the Notranjska valleys, visit the witches' legend sites, and experience the landscape that inspired Valvasor's accounts.
