Chartreuse caving is our reference for adventure.

The route starts at Trou du Graz to travers to Grotte Annette during around 8 hours underground. Jus know that there are other way to cave and traverse Dent de Crolles but this one is the best for us.

It’s a long route, with all kind of technics. Along the progression, the will be a lot of abseiling, until 95 ft high. A very diversified itinerary, sculptured by water erosion. It’s required to get a good physical shape, to have e done at least one caving activity and to have done some abseiling down.

We recommend to do the Eymards cave which helps to learn and practise abseiling techniques and climbing up with Rope in order to be more confident in doing and crossing the Dent de Crolles. Climbing up and down, abseiling down, crawling, hiking on the to do list for this day.

Being in good physical shape is more than necessary, indeed in add to the 8 hours traversing, there is a one hour walking up. All to make you sleep well at night.
