The Great Blue Hole is the most popular dive destination in Belize. This massive hole under the water is near the Lighthouse Reef and creates a perfect circle of deep blue water. The water is 407 feet deep. It's breathtaking.
Caribbean Island of Saint Lucia ( crystal clear water ) = one of the few places that remain untainted by human destruction of our wee blue marble in space / we shouldn't drill holes in the bottom of our only life raft / we have no other ‼️
Giola Lagoon/Thassos-Greece The Giola is a beautiful natural lagoon, like a swimming pool carved into the rocks. The water is warmer than the sea, which makes it pleasant for swimming. The place is unknown and the access there is difficult.
