The Cavardiras Lag da Laus Bike tour includes steep ascents and descents, but without technical difficulties. Once you reach the top of the lake, you can take a breather or even a lunch break. The lake is literally delightful and thus invites you to linger. If you need a little cooling down, you can also jump into the lake.
There are two options for the descent:
Variant 1 is a 2 km long single trail (category black), which is very demanding, or
Variant 2: you forego the single trail and ride back along the same road, in which case it is an easy tour (from a riding point of view).
The start and end point is at Camping Fontanivas in Disentis and the route can be ridden from either side as a circular tour.
