Hi Tony, if you like walking, Afionas is a must. Breathtaking views all the way up and smashing taverna at the end. If you're a little more adventurous there's a track which runs in front of the taverna (Dyonassis), which leads you down to this secluded beach (sturdy footwear required as it's very uneven & steep in places !)
When you've had a rest & recharged your batteries, if you fancy exploring a little further, follow the track that you should be able to see in this photo,
and it will lead you to a tiny little church cut into the rock.
It's a long walk, but if you take plenty of water & make sure you have decent footwear, it's worth it.
