First stage of the: Loop from the Refuge des Conques to the Refuge de Mariailles Mountain hike with beautiful scenery, particularly from Coll de Bise to Collada de la Roqueta. Classified as difficult: exposed, steep slopes in places. See practical information. Allow 6 hours of sustained walking.

This two-day hike, with an overnight stay at the Refuge de Mariailles, allows for shorter variations each day depending on the weather or individual needs. This hike is not fully signposted. However, the suggested variations allow you to stay on the marked trails. Two days in the mountains, from one refuge to another. It is possible to start from the Mariailles Refuge, but add 2 hours from the Coll de Jou to climb up to it.

Most of the walk is out in the open, with some very beautiful scenery. First, a steep climb to Puig de Collada Verda (marker 2403) and a geodesic marker. This is followed by a route along the ridge and a passage to Collada del Vents. Then watch out for the rocky Cingle dels Pelegrins, where there is no fence or protection. Keep away from them by following the path marked on the ground. A large cairn marks the end of the ridge. A return trip to Pla Guillem (signpost) allows you to enjoy the scenery. Classified as difficult due to the length and number of ascents and descents throughout the hike and a dangerous zone (15) at (17).
