Lake Stuben in German; Italian: Lago della Stua[1]) are located 2,423 m above sea level in the back part of the Pflersch valley, which is a left side valley of the Eisacktal.

Similar to the Grünsee, one has to go by car until Ochsenalm (an alpine pasture) and then travel northwards high up route 6 until the lakes are reached after about four kilometers.

As typical mountain lakes, the water remains refreshingly chilly even on hot summer days at max.

The creek has a length of about 1.65 kilometers and belongs to the source rivers of the Fernerbach.

Both lakes give also a protected, untouched living space to trouts and carps.
