This is Hincovo Pleso, the biggest glacial tarn in the Slovakian side of the High Tatras. Just look at the clarity of that water. Gorgeous!
I spent a lot of time watching the fish and simply staring at my surroundings in wonder.
And this is me high above the same lake, on the rocky tippy top of Koprovsky Stit (2367m / 7766ft)
It's amazing to me how low these stunning "high" alpine areas are in Europe. Koprovsky Stit is almost exactly as high as Pinal Peak near Globe, Arizona, where I grew up. Yet Pinal Peak is nowhere near the tree line. The world is amazing.
Hike Details (Round Trip) from Popradske Pleso (the lake and mountain chalet, not the train stop):
Length: 8.8 km
Climb: 812 m
Estimated time: 3 hrs 50 min
Hike Details (Round Trip) from Strbske Pleso
Length: 18.2 km
Climb: 1209 m
Estimated time: 7 hrs
Difficulty: For people like me, the very end is a little scary, because you're so high and you're just sort of clambering over rocks. The trail also has some steep switchback parts. Just take it slow. Trail is closed in winter.
