This dive site, Koh Racha Yai, is an island located about 20 km south of Phuket, offering year-round diving opportunities. It is characterized by diverse underwater topography, with hard corals nestled among granite boulders dominating the Western side, while the Eastern side features gently sloping reefs. Navigation is generally straightforward due to the clear water and gentle slopes, making it suitable for various skill levels.
The marine environment is rich with many species of vibrant reef fish found across all dive sites around the island. Hard corals are a prominent feature, providing habitat and structure for smaller marine life. While no specific large pelagic species are mentioned, the coral reefs teem with typical Indo-Pacific reef inhabitants.
The best time to visit Koh Racha Yai depends on the side of the island being dived. The Eastern dive sites boast the clearest water during the rainy season from May to October, while the Western side is most often dived from November to April. Its shallow average depth and clear conditions make it an excellent choice for beginner divers, snorkeling, and freediving, offering relaxed exploration opportunities.
