The sunny side of Valle Aurina (Ahrntal) Valley Beautiful lake, the northernmost in South Tyrol
From Predoi (Prettau) in the Valle Aurina (Ahrntal) Valley (1,475 m), follow the signage for Waldnersee on Trail No. 16B, across grassy slopes, until you reach the forest. Here, you have two options: You can either follow the forest road on the right side of Wieserbach Creek, which is easier but slightly longer, or take the steep trail going directly up the mountain, following signs for Waldneralm. Eventually, both trails meet again. Continue on Trail 16A and then right on Trail 16B, following the signs until you reach the lake. Avoid the trail; head left to Hundskehljoch. Ascent: 3 hours; descent: 2 hours. There are various options for the descent: experienced hikers can easily find alternate routes for them on the map.
