This dive site, Manta Reef, is located on the east coast of Racha Noi island, which is about a two-hour boat journey from Phuket. It is primarily a wall dive, extending to depths of around 22 meters in some sections, though the primary dive area has a maximum depth of 17 meters and an average depth of 8 meters. Divers navigate along this impressive wall, which is densely covered with various corals from top to bottom, offering a vibrant and scenic underwater experience.
The Manta Reef is teeming with marine life. Divers can expect to see many species of fish inhabiting the beautifully covered soft corals of the wall. As its name suggests, it is also one of the notable dive spots near Phuket where encountering majestic Manta rays is a distinct possibility.
The best time to visit Racha Noi for diving and freediving is generally during the dry season, typically from November to April, when sea conditions are calmer and visibility is at its best. Its relatively shallow average depth makes it suitable for divers of all levels, including beginners, while the potential for manta encounters offers an exciting highlight for experienced divers and freedivers alike.
