Conquer Corsica’s famed GR20 from south to north with an International Mountain Leader, combining hotels, dorms and refuge camping with luggage transfers where possible. We have five nights in hotels, four nights in dorm rooms, and five nights camping in refuges. GR20 accommodation is basic, using small refuges or bergeries with shared mixed-sex dormitories, simple separate bathrooms, and hearty meals. In some locations, tents with foam sleeping mats expand capacity; cleanliness can vary.
