The dune faces the Cap across the basin's entrance — 10 minutes by boat, 1h30 by road around the whole lagoon.
The dune is visible from the Cap — but by road you drive up the whole peninsula, around the basin via Biganos, then down to Pyla and its saturated car park. Over 80 km for 4 km as the crow flies.
10 minutes across the basin entrance from the Bélisaire pier, with the Banc d'Arguin on the way. Landing on the beach at the foot of the dune, tide permitting.
