Why dive here
With 158+ marine species recorded in the area - including blacktip reef sharks, blue-spotted stingrays, mobula rays (devil rays), whale sharks and pufferfish - Shark Island offers some of Gulf of Thailand's richest diving. Water ranges 28-31°C, warmest April, May, June.
Shark Island, or Koh Pung as some call it, sits just southeast of Koh Tao, a rocky outcrop that does vaguely resemble a shark fin breaking the surface. Don’t get your hopes up for big sharks every dive, though we have occasionally spotted a leopard shark lazily cruising the sandy patches, and turtles are a regular sight. The eastern side is generally our pick, with some interesting boulder formations dropping to around 17 metres. You’ll find plenty of smaller reef fish here, and it's one of the more consistent spots around Koh Tao to see orangespined unicornfish. Down on the south side, a soft coral garden at 14 metres adds a splash of colour. It’s a pretty gentle dive, suitable for newer divers looking for a relaxed tour of a classic Gulf of Thailand reef.
