Start the route to Arinsal in front of the Park Interpretation Centre, and walk the first 500 metres on asphalt, steadily going up. Go through the tunnel at the end of the road, then turn right, following the GR signposts, and then you’ll be on a wide track initially, followed by a path, always along the GR and following the signs showing the way to the Comapedrosa shelter.

Cross the streams via wooden bridges, before reaching Colladeta de Comapedrosa after a steep climb. Once you arrive at the shelter, follow the GR signs on the right that will take you to Collada de Sanfons and then to Coll del Port Vell, where you will see the Arinsal winter resort. Then descend until you reach a forest track, where you will start the descent, first gently and later, below the ski lifts, more steeply. This will take you to Les Marrades, a series of zigzags that will bring you down to the base of the resort, on asphalt again. Retrace the initial stretch, now descending, to the starting point.
