From a geographical point of view, the 2,999 m high Mesules High Plateau with the Lech dl Dragon lake is part of the Val Gardena
The Mëisules Peak (Sas dai Ciamorces), one of the less known summits of the Sella Group, rises up to 2,999 m a.s.l. Actually it is a high plateau which is bounded by the Val Lasties valley in the south-east and the Val Pisciadù and Val Setus valleys in the east. The moon-shaped highland can be scaled via the narrow Val Setus valley and the Forcella Ciamorces wind gap.
The Mesules Route (Pössnecker Route), inaugurated in 1912 and therefore one of the oldest via ferrata routes of the Dolomites, however, offers a fantastic view on the Mesules High Plateau. It is accessible from the Passo Sella mountain pass - the path leads in about 7 hours past the Sella Towers to the top of Mt. Piz Selva (2,941 m a.s.l.).
In this area, there’s also the Lech dl Dragon (Dragon Lake), a glacial lake at 2,680 m a.s.l. Its water surface disappears from time to time, as happened in the Seventies and in 2009. The reason is still unknown, but since 2011 the lake has appeared somewhat further to the east. Many legends refer to this lake - one of them tells that a dragon rounds the Dolomites in the sunset.
