    Climbing in the Jura on a natural cliff 15 to 30m high. Fun activity accessible to all from beginner to advanced.

    Climbing is a fun activity. Added to the pleasure of climbing is the discovery of the path to reach the top of the cliff. The spirit of the roped party dominates to ensure the safety of the climber, as does the encouragement to find the holds. The Jurassic limestone, dotted with many holes, is a rock that lends itself ideally to initiation or improvement. So, ready to climb to the top of the Jura cliffs?

  • Canyoning Malvaux

    Canyoning Malvaux

    Proposé par ESI La Boîte à Montagne

    à partir de 40

    The Malvaux canyon located in the Jura is very open and fun with lots of jumps.

    t is a victim of its success with sometimes very high attendance! We advise you to take advantage of the mornings to fully enjoy this beautiful and very playful canyon... This veritable Aqualand that nature has given us is undoubtedly the most playful in the Jura. The jumps follow one another in powerful and very refreshing water! To get there, you will have to dare to jump at least more than a meter (minimum jump compulsory), but you will not be disappointed by its distressing siphon (avoidable!) and its magnificent final waterfall. 5 minutes approach walk and 15 minutes return make it a relatively undemanding physically canyon.
