Tour du Grand Galibier par le col de la Ponsonnière

Precautions:
- The routes you take are your own responsibility. You must choose a route adapted to your physical and technical capacity. If in doubt, do not hesitate to contact mountain professionals.

- Find out about the weather conditions before your departure.

- Be properly equipped to practice hiking in complete safety and deal with the vagaries of the weather.

Tell someone if you are leaving alone and prefer a morning departure so as not to be surprised by the night.
