Club O does have a bathroom in a trailer @100 ft from Lil Perch. Nothing fancy, but clean. The food and drinks at Lil Perch is excellent. Clothing not required, just bring a towel to sit on. Spent two weeks on Orient beach end of March. No issue with daily nude walks before 8am. Just bring a cover if the Gendarmerie come by, but they usually don't hassle nude beach walkers at that time of the morning. Enjoy!
