Summer without beach is definitely incomplete. Especially when you live in a relatively cool city that has some gloomy weather during the summer, an escape to paradise is needed. Let me picture you through my two days 2 nights : Arcachon -> Dune de Pilat -> Cap Ferret trip with the girls.
Far away from the crowds, less tourist than other famous beaches in France. Very relaxing and calm, I would say it’s the best place for vacation if you are looking for close to nature environment, romantic elements, stress free & worry free status or even family time.
Nothing could beat laying on the beach and take a few hours of nap. Feeling the wind, listening to the laughters and waves.
