Magnificent and very useful, dunes embellish the Rétais scenery for over 20 kilometres.

They are the ideal setting for iodised walks or an introduction to the pleasures of the beach: here is an open space to be preserved! Marram grass is planted so as to protect dunes from climatic attacks …

Branches on the soil and "garnivelles" - lattice fences - are used to stabilize the sand….

"Sand dunes? I love admiring them but I never climb them… It’s forbidden and anyway I want to protect them!"
