France into Spain

This was the first time we have stayed in a Forestry Campsite in France. For your 6 euros you have the use of toilets and a set amount of water to put in your motorhome (approx 100L I think - we didn't need any water having filled up at the last free campsite). It was a large camping area and about 10 minutes walk over the dunes to the beach. Only about 5 other campers were there with us but I am told it is completely full in the summer months.
