Cars, crowds and beaches are beautiful. Tourists swimming at Paradise Beach on Mikonos Island are advised to be careful of a reef barrier that protrudes about 30 centimeters from the surface of the water at about 30 meters offshore. Because I couldn't see it on the surface of the water, I swam freely to this time. There were many cuts in my hands, stomach and legs, and a lot of blood was shed. Here's a picture of a scar that hasn't healed in eight days. The black beach on Santorini Island is flat and comfortable. You can rest assured and swim boldly.
