The High-Mountain Office team welcomes mountaineers and hikers all year round and provides them with up to date moutain information.
The High Moutain Office (OHM) was set up by the Chamonix guide Gérard Devouassoux. Following a particularly distressing mountaineering season in 1971 people wanted to find a solution, which would preserve freedom but also would limit and reduce mountain accidents.
Opening hours on Monday, Tuesday, Wednesday, Thursday, Friday and Saturday between 9 am and 12 pm and between 3 pm and 6 pm.
Closed on Sunday.
Closed exceptionally on January 1st, November 1st, November 11th and December 25th.
