Lovely surrondings of Arcachon becomes horrendous in July if you try to get anywhere — it takes nearly 3 hours to get from Arcachon to Andernos Le Bains in the early evenings. In fact, if you want to go anywhere in the area in summer, you'd better start early in the morning around 9AM. This is not a place for those preferring laziness in the mornings while on vacations.
