From Guérande (10 kilometers), proceed in the direction of La Turballe (Pen Bron).
After exiting Guérande, turn left towards Pen Bron. The beaches are marked. Proceed past a small bridge and then at the barrier park on the right (the barrier is only present during high season). Alternatively, you can follow the campsite. Cross the pine forest to reach the dunes.
You will encounter a highly populated sandy beach with a designated family naturist zone and a gay nudist area.
