Here is the equipment you will need to climb outdoors.
A crash mat is designed to soften your fall.
We recommend you use a thick one with a large surface, even if it's a bit more bulky.
A guidebook (or topo in French), will help you navigate climbing areas.
We recommend you use the Boolder app. You will have access to a GPS map and photos of the problems.
If you prefer a paper version, we recommend using Fun Bloc.
Also, feel free to take a sports outfit that doesn't restrict your movements too much, and some food and water.
