From Altiport bus stop, carry straight on behind the buildings to find the beginning of the trail. Start by following signs to Rhodos walk under the Loze chairlift and take the path on the left signposted to Pic Noir.
Please note: The Col de la Loze is not accessible on foot in winter, but you can get there by taking the Loze chairlift (remember to buy a ticket at the Altiport lift pass office).
