Where is it ?

The first ones dévaleurs are in rent on the spot "Source du Doubs".

You can make out a will on an easy track with a little slalom.

Price of ten ascents:
9 euros (adult version).
6 euros (kid version).

In fact, devaling can be practised on all the classic ski runs, normally opened to snowboards.
Any particular adaptation is superfluous.
It is enough that the ground is grassy enough and without stones, with the minimum of soil erosion.
Only a regular mowing is advised during summer.
It is so useless to realize specific tracks as those for mountainbike.
To note that the best tracks are situated above 1500 m of height, there or it is less often raining in spring.
