We used to swim in Kamari beach while we were on holidays on Santorini because it was close to our hotel. The walk to the beach was enjoyable and the good thing is that Kamari is close to many amenities, like mini-markets, taverns and cafes. Kamari has very clear waters and umbrella rentals. I liked practicing pedalo and jet ski there. It was much fun, we usually spent all day at the beach!
