Hi Mike and Shaz. Look at the interactive map (Maps in the menu on the website) and you will see that Leonidas is near a group at the edges of the village (Tria Adelphia, Tropicana and Elena Stella (where we stayed for a month last September) and others. Agree with Paul - about 15-20 minutes walk from the sea, whether you go left or right. One will take you past the Rainbow, Brouklis and into the centre, the other past Vavilas fish restaurant (superb!) and out past Bardis Sun to Sea Breeze and Grazella (also a fabulous eating place.)
Access to the naturist beach is easy - to your right as you face the sea and an easy walk along the sand.
Nowhere is far away in Arillas, but some prefer those near to the beach, some the ones up the hill, some right in the middle. If you want info about others just keep posting. Someone here will know your answer.
Good luck with your first time. If you're like most it won't be the last...
Phil
