Nunayak presents: Hydrospeed in Haute-Savoie

Let yourself be carried away by the river!

Hydrospeed in the French Alps in Samoëns on the Giffre River, in the Mont-Blanc region !​

Swimming in the rapids is a funny way to understand and to demystify the river. To practice hydrospeed, you will be given palms, an amphibious float in foam, a helmet, and a reinforced wetsuit. Your guide will tell you how to maneuver in the rapids to find your way. Your fear to fall into the water is gone then…

Swimming in the river won’t scare you since you will be an expert after a hydrospeed session !

Hydrospeed information

Hydrospeed on the Giffre River

The Giffre River is located in the Haute-Savoie Region and more precisely in the Samoëns Valley. It takes its sources in the  Cirque du Fer-à-Cheval (classified “national park” as a natural reserve). The Giffre River flows in the very heart of an exceptional Valley that is surrounded by an incredible ancient geology. 

You’ll get to know the Tines Gorges, which are a 40-meter deep canyon in which only rafting and other white-water sports can access this spot.

So, let’s get started with Nunayak !


  • Be healthy and know how to swim
  • Wear a swimwear and bring a towel
  • Be strong enough to be able to put a reinforced wetsuit on your own
  • Have read and accepted the rules
  • Be happy, smiley and excited !
