A project is nearing completion to renovate the Tour Rouge hut. Jean-Se is still looking for contributions. The old hut was destroyed in the 70s but there may be some on this site (!) who still remember it.
Jean-Se has done a great job recently of replacing the the little hut just above the Bréche de Puiseux as well.
