The trail starts at a sharp bend on the L-501, just beyond the Pla de l’Ermita and before the San Martí Bridge, where a small parking area is available. From here, follow the signs to Port de Rus, which initially coincide with the GR trail. The path winds through a forest before gradually ascending through alpine meadows, leading to the mountain pass a natural link to Cabdella in the Vall Fosca.
