To get to the start of the hike from Le Boulou, take the D900 towards Le Perthus. At the first roundabout, take the third exit towards the casino. Park in the casino car park, at the top left of the casino.
(S/E) Head south-east along the track that runs alongside the car park on the right. Head towards the building with the sign on the front: "Les Eaux du Boulou". At the next crossroads, turn right and head south-west for about 100 metres.
(1) Take the path that descends into the forest on the right, heading due west. A few dozen metres further on, the path branches off due south to the Saint-Philippe Chapel. After visiting the chapel, continue a few metres further south to discover the Font Sant Marti.
(2) Leave Font Sant Marti by retracing your steps to the Saint-Philippe Chapel. Then turn right, heading due east to join the Puig Estella track about 100 metres further on. Take the track on the right, heading due south.
(3) Cross the Còrrec de la Siureda and continue south on the left. At the hairpin bend 100 metres further on, stay on the track and ignore the two paths that branch off to the left.
(4) At the next two junctions, turn right. Leave a track on your left, and at the next junction, at the exit of Mas d'en Peixeira, turn left heading due north.
(5) Leave the track on the right to pass by a water reservoir and enter Les Thermes du Boulou. Continue north-east to reach the Casino car park.
Return to the car park by going around the Casino on the right-hand side of the establishment (S/E).
