Močilnik is a scenic valley where water from several subterranean streams comes to the surface and forms the sources of the Ljubljanica river. It is lined by overhanging walls of rock known as Devil's Crags (Hudičeve skale). In a corner of the valley, above a bridge, the so called "Jason's Fistprint" is impressed into solid rock. Močilnik, where a restaurant and guesthouse welcomes visitors all year round, is considered to be a place where Ljubljana Marshes blend into Slovenia's karst region of Kras.
