Beaches near Essaouira, Morocco, are famous for its excellent conditions for surfers of many kinds.
The beach shown on the map here apparently is not used a lot, 
so you could try nude surfing… Or jogging,
or just sunbathing,
whatever you like.
… like a handstand?
As the water is cold there because of the upwelling, you can’t swim too long. And the waves are really strong too.
At the low tide, rocks covered by bright green algae look surreal contrasting with yellow sand of the beach.
If I go there again, I should do some surfing, however!
