This little lake deserves a stop, especially now in June when everything is in bloom. It's perfect for a snack or peaceful break surrounded by birdsong. Right between Capbreton and Bayonne.

Peaceful, magnificent, back to nature near Biarritz… There are small dirt roads next to it or a tarred road. Far from the tourist crowd.
