The High-Mountain Office team welcomes mountaineers and hikers all year round and provides them with up to date moutain information.
DescriptionThe High Moutain Office (OHM) was set up by the Chamonix guide GÃ©rard 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.
