Red Beach, Santorini
Photo Courtesy of Erin JonesIt's secluded, or as can be on a famous island. If you are there in non-peak months (Nov-Apr) you are almost guaranteed to be alone or close to it. I was there in Nov and was the only one for an hour!
You have to do a little precarious hiking to get to the beach proper, and it's fairly small, as far as beaches go, but the sands are an amazing rust-red color and the waters are of choice temperature. So unique!
Definitely in my top 5.
