Why dive here
With 173+ marine species recorded in the area - including blacktip reef sharks, eagle rays, giant moray eels, whale sharks and clownfish - Racha Noi Island offers some of Similan Islands's richest diving. Water ranges 29-31°C, warmest April, May, June.
Racha Noi usually delivers some of the best visibility around Phuket, making it a reliable spot when other sites are a bit murky. We often head to the northern and southern points, where those huge granite boulders create impressive swim-throughs and channels, much like what you’d find in the Similans. It’s a good place for a drift dive, letting the current carry you past schools of fusiliers and triggerfish. Keep an eye on the blue – manta rays make regular appearances here, and we’ve even had a few whale shark surprises over the years. This site is a solid choice for divers who appreciate dramatic underwater topography and the chance for big pelagic encounters.
