An 800-hectare area of dunes has been set aside as natural environment and nature reserve zone. And for good reason !These ancient dunes are extremely fragile. The vegetation cover is thin and even the slightest disturbance will expose the sand dunes to wind and erosion. The trampling of too many feet and the use of all-terrain vehicles can cause blowouts (disturbed areas where plants are not able to grow back). For this reason, motorized vehicles, fires, littering and hunting are not allowed in the dunes area.
