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 Yai Wreck offers some of Similan Islands's richest wreck diving. Water ranges 29-31°C, warmest April, May, June.
Okay, let's set the record straight on the Racha Yai Wreck. Forget what some of the older guides say; this isn’t a deep, dramatic tomb of a ship. It's a series of purposefully sunk vessels, mostly fishing trawlers and patrol boats, resting on a sandy bottom. We actually really like it as a multi-level dive, especially for those looking to get comfortable with wreck penetration without the serious overhead. You’ll find the main attraction, a sizable passenger ferry, sitting upright. The upper deck is around 18 metres, and it slopes down to about 25 metres at the stern. Our favourite part? The wheelhouse. You can easily swim through, watching the sunlight dapple through the portholes, sometimes catching a resident giant moray peeking out from a dark corner. Schools of yellow-lined snappers practically form curtains around the masts, and we often spot lionfish perched dramatically on the railings. It’s not a site for massive pelagics, but for critters and exploring the nooks and crannies of a colonised wreck, it’s a solid choice. Go early in the morning before the day-trippers arrive for a more serene experience.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
