Visitors can dive under the icy surface of Lac Lioson in Les Mosses. A must for all diving clubs! Any thrillseekers wishing to take part must bring their diving certificate and assume complete responsibility for their own safety. The three access holes are laid out in a triangle formation and are well-maintained, even in the winter season.

How to get there:
By car: take the A1 motorway and exit at Aigle, then follow signs for the Col des Mosses.
By public transport: take the Aigle - Sepey - Diablerets train from Aigle railway station, alight at Sepey. From Sepey take the post bus to the Col des Mosses.
