You will meet your guide at Montenvers station: the adventure begins as soon as you set foot on this unique cogwheel train! You gain height among the peaks and enjoy an impressive view of the Chamonix valley. You pass at the foot of the Drus and the Grands Jorasses and contemplate the most beautiful things the Alps have to offer… It is then time to arrive in front of the largest glacier in the French Alps, at 1,913 metres above sea level. This memorable encounter is punctuated with historical anecdotes, as well as stories from adventurers who set out to explore this emblematic landscape of Chamonix-Mont-Blanc. An integral part of the Vallée Blanche ski descent, the Mer de Glace is a real playground for thrill-seekers! Your guide also guides you in discovering the mythical peaks that surround you… Discover even other riches of the mountain in the crystal gallery which conceals natural treasures and, depending on the opening conditions, enter the heart of the glacier with a visit to the Ice Cave... You are not at the end of your surprises!
