June 17, 2025,Hike Le Chinaillon (Fr) - Lac de Lessy (H/T) 10/10
Fantastic hike! Required: hiking boots type B - sturdy hiking poles - good condition!
This hike is highly praised in the region!
Not particularly difficult, but at times very technical and especially there are a few sectors that are quite steep! The atmosphere during this hike is unparalleled! A super and even more a wonderful day in the high mountains!
