Hi smilingtoday. Welcome to our community. The naturist beach is largely regarded as the north end, past the little rock outcrop. It is not officially recognised but has been used for many years. It is a bit of a walk from the steps outside Kaloudis, but not far. Many use the quiet parts of the south end (turn left from Graziella steps.) Both are a flat walk on the sand, but last year it was a bit more difficult to get there. There are many lovely posts in the beach board - just hit Home on the forum and head for the Beach item. Our viv's Nudee Beach Bum thread is worth reading. As you might guess, Jen and I use it a lot....
As for Mythos, if experience counts for anything, I am an expert. I have never had a warm one. The tavernas who do draught always freeze the glass, and the owners who don't will not serve one that hasn't been chilled long enough. I am being honest here. I have drunk Mythos in just about everywhere in Arillas and never been disappointed.
From reading your post, I feel sure you are destined to become another Arillas Addict. Your list will be delivered in bucketloads...
