Very disappointing refuge. They're a nuisance when you ask for the weather or the slightest route information. Unpleasant welcome and pushy consumption: the bivouac sites around the refuge are only accessible if you've booked a dinner... and it's impossible to book a dinner on the same day on site! This makes no sense. After talking with other hikers and local people/professionals, this seems normal, and the warden's reputation precedes him... Too bad.
