OHM is the place to be for hikers and mountaineers. They are welcome to report on their recent mountain experience on our alpine report book “Cahier de courses” so to share information and maintain a genuine cohesion spirit. 


Visitors can freely access guide books and topographic maps. A 1/10 000 relief map represents the Mont Blanc range at a miniature scale can also help visitors in their research.


The OHM offers access to all types of information necessary to prepare a day out in the mountains:

  • Mountain huts (opening periods, trail access, contact…)
  • Mountain lifts (location and access, opening hours and periods…)
  • Alpine regulations (bivouacs, wildlife sanctuary, paragliding, speed-riding…)
  • Presentation video


OHM recommends mountaineers who have no particular contact in the valley to inform about their route choice and the planned dates.
