One of the best day hikes in the Dolomites is by far the hike to Lake Coldai to Rifugio Tissi. The 6 hour roundtrip hike starts from the top of Col dei Baldi above the village of Alleghe to the stunning Coldai Lake, passing the northwestern flank of the mighty Civetta until we finally reached the Rifugio Tissi. If you have one tough hike in you, this is the one to do.
