The back and forward lakes Stubensee (lit. Lake Stuben in German; Italian: Lago della Stua) 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.
