Črna Prst is a mountain in the southeastern Julian Alps, located at the edge of Triglav National Park. Standing at 1,844 metres (6,050 ft), it is the 370th–highest peak in Slovenia. In the interwar period, the mountain ridge marked the border between the Kingdom of Italy and the Kingdom of Yugoslavia.

The Via Alpina is a network of five long-distance hiking trails across the alpine regions of Slovenia, Austria, Germany, Liechtenstein, Switzerland, Italy, France, and Monaco. The longest of trails is the red trail, whose termini are in Trieste and Monaco.
