Equipment on the GR20

There is no opportunity on this trip to buy new equipment. Ensuring you have the right gear is essential for everyone’s safety.   It can be equally dangerous to carry too much gear that is not useful.  If you are weighed down this adds to fatigue and you will be unable to accelerate your rhythm in bad weather.

There are repellants available, that you can spray on your rucksack or sleeping bag before you come, if you know you are susceptible to bites.
