Planina Cave information
Planina Cave, 12km to the northeast of Postojna Cave, near the unpredictable Lake Planina, is the largest water cave in Slovenia and a treasure-trove of fauna (including Proteus anguinus ). The cave’s entrance is at the foot of a 100m rock wall. It’s 6.5km long, and you are able to visit about 900m of it in an hour. There are no lights so take a torch.
Caving treks (€30 to €60) to Planina and other caves in the area, that last between three and six hours can be organised through the Sport Hotel .
