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 - Koh Ran offers some of Gulf of Thailand's richest diving. Water ranges 28-31°C, warmest April, May, June.
Koh Ran in the Gulf of Thailand gives you a relaxed dive with plenty of small stuff to spot. We’ve seen cuttlefish here, along with groupers tucked into crevices. It’s a good choice for newer divers or anyone looking for a chilled-out afternoon underwater, especially if you appreciate macro life over big pelagics.
