On the border ridge between Italy and Switzerland (Canton Ticino), descending from the important summit of Basodino, there are several not very known mountains: one of those is Pizzo Stella or Martschenspitz 2688 m. Pizzo Stella is located at the beginning of Formazza Valley and, to the Swiss side, just above of village of Bosco Gurin, the only Walser language enclave in Tessin. The Walser colonizers entering from Formazza passing through the Passo di Bosco or Guriner Furka 2323 m in 13th century; the pass is located at the beginning of south-west ridge of Pizzo Stella. But perhaps the most interesting reason to go here is located in the west side of the mountain, the beautiful little Lake Superiore 2254 m.
