Lake Cerknica is an intermittent karst lake in the Primorsko-notranjska region, near the town of Cerknica. Depending on the season and rainfall, it fills into one of the largest lakes in Slovenia or drains away through underground karst channels, leaving meadows and fields. The flat surroundings suit easy walks and cycling along the shore and across the lake basin.
Cross Cave (Križna jama) is a karst cave in the Primorsko-notranjska region of Slovenia, known for its chain of underground lakes and its rich cave fauna. It is one of the country's best-known caves and is visited in small guided groups rather than on paved walkways. The cave lies on the karst uplands near the Lož Valley, a short drive from Cerknica Lake.
Snežnik Castle is a medieval castle in the Primorsko-notranjska region of inner Slovenia, set in the Lož Valley area of Notranjska. It is worth a visit for its well-preserved castle architecture in a quiet rural setting surrounded by meadows and forest. The castle makes an easy stop on a day trip through the Notranjska karst region, with short level walks around the grounds.
Planina Cave is a karst cave in the Notranjska region, near the village of Planina by Planinsko polje. It is a water cave, where underground rivers flowing through the karst meet and emerge as the Unica river. The cave lies a short drive from Postojna and suits visitors interested in the Notranjska karst beyond the better-known show caves.
Cerknica is a lake in spring and a meadow by late summer — check the season before you promise anyone water. Križna cave takes small groups by lamp; the short tour needs no booking, the long boat tour does. Planina cave is a short walk from the car park at the end of the Planina field.
