We do have a couple of small ones (<20m), but from the looks of it they're way too crowded and always booked out. I'm also a pretty good swimmer, so just stumbling back and forth trying to get through the crowd is not interesting to me, and it looks like there are no 50m or even 25m naturist pools here. Which is sad, I'd absolutely love to visit it from time to time (I still prefer to sleep at night haha).
