Completely answered Val. The naturist North end is beautiful, but totally unofficial. Apparently it takes a couple of wades through the sea this year after you turn right past the steps outside Kaloudis. But it is flat, and relatively easy to get to compared to many. Many of us use it. No sunbeds, just nature.
But Arillas offers a lot more than just that. Start with the food for example. But in the end it is the locals who make it what it is. The people of Arillas are basically why most of us on this forum keep going back year after year. Many are truly our friends, not just our hosts.
