Italy
A beautiful little glacial lake at 7,000ft that sits below Monte Civetta. Its surrounded by dramatic rock edges and there's a welcome cool breeze when it is accessible in the summer months. The gradient from Palafavera, just north of Pecol is fairly steep, although you can take a ski lift almost half way to the top.
Coldai is along the path of the Alta Via 1 trek through the heart of the Dolomites. You pass Refugio Sonino along the way, where you can get food and a bed for the night if needed.
Refugio Tissi further along is also a great place to stay. But the walk up to the lake and back down could be a day trip from either Palafavera or from Alleghe on the other side of the valley.
The views of and from Lago Coldai are spectacular and the lake is a welcome rest spot, or bathing spot seemingly, if you are one of several eccentric Spanish ladies.
