The Lucifer Waterfall near Gozd Martuljek filled with water from the Zapreta Mountain is certainly the most “sinister” waterfall in Slovenia.
In summer, it is only a modest waterfall over the steep ‘Mokra peč’ rock face.
In winter, the waterfall freezes and becomes interesting for ice climbers. It is the first climbed waterfall in Slovenia. There are many more demanding ones, however the ascent over it is still an exciting experience.
You can start climbing the original Right Leg path, and then follow the combined directions with original names like Angel, Three Confused Days, Luis Cypher...
