Park in the car park at the lighthouse, located 1 km away.
(S/E) Take the path on the left to walk along the Étang du Tampan on the right and the Étang de Galabert on the left.
(1) Continue on the path furthest to the right.
Keep right at the small three-way junction and, at the next intersection, go straight ahead on the path towards the beach.
(3) Turn right. The lighthouse is on the right and a vast beach stretches out in front of you, all the way to Les Saintes.
(4) Turn right towards the Dune des Douanes. Walk about 500 metres across soft sand, which will sink your feet a little. In winter, there is a ford to cross with water up to your ankles before you reach the Dune des Douanes path, as the water from the ponds rises through capillary action.
(5) Follow the path straight ahead and join the junction with Chemin de la Digue à la Mer.
(6) Turn right between the ponds and salt marshes. You will reach the Gacholle lighthouse.
(7) Continue straight ahead to the car park (S/E).
