Parking is available at the main entrance, at the Marmande car park, or you can cycle there from the car park or from Lacanau-Le Moutchic or Carcans-Maubuisson.
Bicycles must be parked at the entrance to the lake; please bring a padlock.
(S/E) From the Marmande car park, head due east and follow the tarmac track (recently built cycle path) for about 500 m until you reach a fork.
(1) Turn right to join the more picturesque footpath (former cycle path). The two paths will cross several times.
(2) Cross the tarmac track to continue along the footpath opposite.
(3) Cross the tarmac track again and head towards the Carrefour de Cousseau.
(4) Continue straight on, due east, until you reach the entrance to the nature reserve.
(5) Then follow the signposted path to the right (Lesperon Tower). Walk around it and finish at the Galip Tower.
(6) Turn left and return to the entrance to the nature reserve.
(5) Head back in the opposite direction to the way you came.
(3) There are two ways to reach the Marmande car park (S/E):
- either continue in the opposite direction to the way you came,
- or take the tarmac track for a change, though it is less pleasant.
