THE GREEN LAGOON
This bright green lake fringed by a black sandy beach looks just like something off the set of an old episode of Star Trek, but it’s actually a lagoon that formed in the crater of a volcano which erupted in the 18th century. Although lagoon and ocean are connected by undersea tunnels, the lagoon’s water is so still it invites thick algae, creating this trippy Chartreuse hue. It’s protected by a fence to stop swimmers, but only a real space case would attempt to dive in.
