Koh Yippon
An island and rock group at the northern end of Mu Ko Ang Thong Marine Park, one of the park's most visited dive and snorkel areas on day trips from Koh Samui and Koh Tao. Operators describe shallow swim-throughs and a roughly 20 m long cave across the island's eastern tip that is fully submerged only at high tide, plus soft corals and sea fans. Fusiliers, yellowtail barracuda, snapper, blue-spotted stingrays, banded sea snakes, white-eyed morays and cuttlefish are mentioned, with a resident turtle seen now and then.
depth: None–18 m
