Black Sand beaches in Greece
The beach has this amazing great rock on one side, fun black sand, few people in low season (September), clean water, no pebbles problem. Pebbles are a problem on most Santorini beaches - getting in and out of the water is a pain without special footwear, but not in Perissa.
The water temperature in September gets comfortable when you get used to it a bit. Clean and clear. Loved the food, service and prices in Aquarius - one of the numerous places to eat right next to the beach. they treated us with refreshing compliments, huge tasty portions & great attitude. We had greek salad, tomato soup & pork chop. All shared - that's enough to get full in Greece. 25 euro for two.
Few people walking around selling goods & massages are not as intrusive as some reviewers say. There are places in the world where you get much more distraction in beaches. Here vendors would just walk around quietly.
