Start: drive through Fontarrabie to the end of Cap Figuier (Cap Higer in Spanish) and park in the campsite car park.
(S/E) Take the path from the car park at the far end, which passes over the water treatment plant. Reach the path junction at Depuradora.
(1) Turn right onto the GR®121, marked in Red and White. Follow this coastal path to the water station, crossing a small stream.
(2) Do not take the path that runs perpendicular to the coast, but continue on the GR® until you reach a lovely view of Artzu Portua cove. Go as far as the junction of the paths.
(3) Take the left-hand forest path that runs along the contour lines. The path meanders, crossing the Martierreka, Kapelutako Erreka and Erreka streams before reaching the Depuradora crossroads.
(1) Return to the campsite car park (S/E) along the same route as the outward journey.
