With an ethereal minty tint, the Emerald Lake (also called the Blue Lagoon or Inner Sea) on Ko Mae Ko is a large lake in the middle of the island that spans an impressive 250m by 350m. You can look but you can’t touch: the lagoon is strictly off limits to the unclean human body. A dramatic viewpoint can be found at the top of a series of staircases nearby.
