Giola, Thassos, Greece. The lagoon, located near the village Astris, is often called the most natural swimming pool. Indeed, it is a unique water reservoir, which provides a pleasant swimming experience.
You may have heard about the island of Thassos already: the mythological Syrens, who have attracted sailors with their beautiful singing, have resided here. The Aegean Sea rinses its shores and fills the pool with water. But since the pool is separated from the sea with a rock wall, the water in the lagoon is much warmer, making it much more pleasant to dive in.
