Some additional information about the circular loop:
Difficulty: Moderate with some fairly steep climbs; walking poles are strongly recommended.
There may be snow in May and gusts of wind on the numerous ridges and passes along the route; I advise you to bring warm and/or windproof clothing.
Please note: at the start of the second stage (Col de la Croix Morand – Courbanges):
to avoid walking alongside a main road, you can take a shortcut – a pleasant, scenic 500m off-trail section – but waterproof footwear is advised, as the ground can be a bit marshy during wet spells.
Water sources: there are plenty; on the third day, you’ll find the Source Sainte-Anne, among others, and several waterfalls nearby (bring a water filter or purification tablets in these cases); otherwise, you can fill your water bottles in the evening at the refuge.
