Tips from the Community
Raibl is connected to the Slovenian village of Log pod Mangartom (formerly in German: Mitter-Preth or Breth) by a 5 km long tunnel, which runs under the Predil Pass and through which the miners from Log pod Mangartom used to go to their shift in the Raibl mine. During the First World War, it also served to supply the Isonzo Front under the name Kaiser-Franz-Josef-Hilfsstollen.

Raibl is the starting point of the road over the Predil Pass to Bovec (German: Flitsch) in the Slovenian Soča Valley, as well as over the Nevea Pass and the Raccolana Valley to Chiusaforte. Raibl is the starting point for numerous mountain hikes in the Western Julian Alps (Kanin area, Montasch and Wischberg groups). The local mountain is the 2122 m high Raibler Seekopf (Cima di Lago). South of the village lies the cold, dark, mountain-framed Raibler See (Lago del Predil). Approximately in the middle of the northwest shore, before the First World War, stood the Austrian Raibler Seefort, which secured the imperial border that ran through the Seebach Valley.

The village is located at an altitude of 900 m and is characterized by the lead mine, which was closed in 1991. Until the end of the First World War, the village, like the entire Canal Valley, belonged to Carinthia and was predominantly German-speaking. In addition, Raibl had a minority of Slovenian inhabitants due to mining, who came from the Koritnica Valley and went to work through the tunnel under the Predil Pass. In 1918, Raibl fell to Italy. After the resettlements under Mussolini, the village is almost exclusively Italian-speaking. Cave del Predil is today a fraction of the municipality of Tarvis and still had 2100 inhabitants in 1968. After the mine ceased operations, the population decreased rapidly, and in 1999 only 450 people lived in the village.
