Start: From Col de la Forclaz (large car park).
(S/E) In the bend at the Col (pass), take the path heading south along the Bisse du Trient (signposted).
For the rest of the walk, follow this false-flat path as it rises along the Bisse. You will see a number of information panels explaining the origins of the trail in ice mining, as well as activity games provided by Charlotte la Marmotte.
(1) After about ten minutes, you'll come to a crossroad cont. Continue straight on towards the Glacier du Trient.
Gradually the panoramic view will include the Col de Balme to the south-west... then onto the Glacier du Trient and the Petite Pointe d'Orny. Continue straight on along the Bisse until you reach the Chalet du Glacier.
(2) For the return walk, take the same route down. Allow between 45 min and 1h to return to the Col de la Forclaz (S/E).
