OverviewThe traverse on the Bionnassay ridge is a great alpine route to the Mnt Blanc, starting in Italy. Its also a slow approach of the mountain, you can get up to the summit without using any transport. The Bionnassay ridge itself is a very narrow snow ridge that connects Aiguille de Bionassay with the Dôme du Goûter. At some points its only one foot wide.
Although the route technically is not too difficult (only for experienced mountaineers), it is very exposed and you need a window with 3 days good weather at least, to climb it. In july 2007 six people died by falling of the ridge, or during bad weather at the start. Extra attention needed for corniche break during the traverse on the ridge.
