Most scuba access is by short boat runs from Koh Ngai dive shops, and the dry season gives the most reliable visibility and easiest logistics.
About Ko Ngai
Ko Ngai is a quiet Andaman island dive area with shallow reef-and-rock sites around the southwest coast and nearby reef slopes. Trips are short and relaxed, with easy profiles, coral-encrusted structure, and regular sightings of barracuda, moray eels, turtles, and blacktip reef sharks. Plan for the dry season if you want the clearest water and the smoothest boat runs.
