On Santorini, because of the volcano, there are many different types of sand and rock. There is a red, black, and white beach.
We only made it to the one beach, but it was still fun. Not too many people that early in the morning and lots of pretty smooth stones along the beach.
We took the bus back to Fira where we walked around and shopped a bit more. The cruise ship people were out in full force, so we took refuge from the throngs of people in a restaurant.
We ordered a really fantastic meal and enjoyed the view down to the port.
