The northernmost area around Resia Lake retains its own fishing rights. In adjacent S. Valentino Lake, one of the most beautiful natural lakes in the Alpine region, fishermen can also find a place to cast their lines free of care. For fishing in S. Valentino Lake, a fishing license type B or D as well as a fishing card for the day will be required. You can purchase the daily card directly at the boathouse at Fischerhäuser/Casa dei Pescatori, at Alpenrose Inn, or at Bakery Angerer in the village center of St. Valentin a.d.H./S. Valentino alla Muta.

The typical fish species in the home waters are veined trout, river trout, rainbow trout, brook trout and grayling. Smaller fish species can be found in the mountain lakes. The fishing season on Lake St. Valentino begins in late April, while in Lake Resia the season starts in mid-May. Tourists may obtain a fishing license, valid for 10 years in Italy.
