The lake in the heart of the hiking and mountainbiking mountain area Corviglia can be used as an oasis of relaxation or as a running track for the individual altitude training.
The lake of Lej Alv above Marguns captures and stores the water that flows down the mountain and the Val Schlattain during the snow melt. In winter the lake is used as a reservoir for the artificial snow on the mountainside; in summer it provides a wonderful excursion destination for mountain bikers and hikers. You can reach the lake on foot or by mountain bike via the mountain station of the Marguns gondola or the mountain station at the Corviglia funicular. Given the altitude, swimming in the lake is an option for hard-core bathers only; but its shores do provide a delightful relaxed setting for a picnic lunch as you take in the views of the Engadin mountains and savour the crisp mountain air. The Lej Alv is also ideally suited for altitude training, with a Finnenbahn cross-country running track circling the lake – a wonderfully healthy option for joggers and other endurance athletes to train on.
