Wondering where the disappearing waters of Lake Cerknica go? Well, they re-emerge 6km west of Cerknica in the form of the Rak Creek in the natural wonderland that is the Rakov Škocjan Regional Park. Stretching some 2.5km the Rak gorge cut out by the creek is packed with interesting geological formations including the Zelške Caves from which the waters spring and the Tkalca Cave where they again disappear underground, whilst in between are the impressive little and grand natural bridges (mali/veliki naravni most), where over the centuries the creek has hewn out impressive arches in the rocky Karst landscape. Rakov Škocjan, which is part of the Notranjska Regional Park, also contains some archaeological sites such as the ruins of the early 17th century St. Cantianus’s Church. A well maintained path that takes in all the park’s main attractions with an easy round trip taking about 4hrs - just be careful when traversing the river and exploring the caves as it is often slippery.
