Orrido dello Slizza

Orrido dello Slizza is a deep canyon near Tarvisio carved by the Slizza torrent over millennia. A marked trail with wooden bridges and rock tunnels winds for about an hour along steep canyon walls and emerald-green water, passing small rocky beaches and carved stone galleries.

The Orrido dello Slizza was carved by the Slizza torrent over thousands of years into its present form. The canyon historically served as a passage between Italy and Slovenia, and around 1900 a railway bridge was built through the area, remnants of which remain visible today.

The name Orrido dello Slizza refers to the Slizza torrent that carved this canyon over thousands of years. Today, visitors notice how local people use small sandy spots along the water to rest during warm months and how the site serves as a connection point between the Italian and Slovenian regions.

The trail is well-marked and takes about one hour round trip with minimal elevation change. Wear sturdy shoes as rocks can be slippery, especially after rain or in autumn when leaves accumulate. The path is open year-round but may have icy conditions in winter.

The trail passes through a tunnel carved directly into the rock and past remnants of a railway bridge built around 1900. This historical infrastructure reveals how the canyon has long attracted people seeking to cross and connect with neighboring regions.
