Access to the naturist areas can vary with the weather, you may have to wade through the sea, but it is all flat. I have been to many naturist beaches that are much tougher to get to, at the bottom of a cliff or with miles to walk to etc.
Arillas isn't a "naturist destination" as such, and has so much to offer textiles and naturists alike. But you can be a peaceful and happy naturist there. Jen and me do... ten times so far. Number 11 coming up in July
