(2) Leave the D2 and turn right onto the tarmac Chemin de Saint-Marc until you reach the gate of the last house. Continue along a wide track, ignoring the adjacent tracks on your left. Continue climbing along the main track for 1.2 km until you reach a track branching off to the left at a 90° angle to the south.

(4) Turn back to the previous fork.
(3) Turn right and head uphill to the south, passing a track on your right, and you will soon come to a Y-junction.
(5) Take the right-hand track uphill, heading due west, and you will come to an intersection in a sharp left-hand bend.
(6) Leave the track and climb steeply up the small path (north) towards Mount Helena. The path turns left (west) when it reaches the ridge. You will eventually reach a track suitable for vehicles (elevation 768).
(7) Continue straight ahead to Mount Helena, where there is a fire lookout tower.

(13) Follow it to the left (north) for a long time. Pass Can Malet, Mas d'en Figuera, and arrive at an intersection of two roads (elevation 389).
(14) Take the D2 opposite and return to a fork you passed on the way there.
(2) Continue straight ahead along the road and, following the same route as on the way there, you will arrive at the car park below the town hall (S/E).
