This dive site, Racha Noi Bay, is situated on the east side of the South Island of Racha Noi. Divers can navigate offshore from the beach, where a prominent formation of large roots and megaliths, folded upon each other, defines the underwater landscape, running from north to south. The depth around these megaliths ranges from 10 to 25 meters, while smaller roots are scattered in the shallower sandy areas. The megalithic zone is the main point of interest, featuring a distinctive long slot on its south side.
The bay is renowned for its exciting marine encounters. Manta rays are known to appear in the deeper areas off the megaliths, at approximately 25 meters. Zebra sharks are frequently sighted in the comparatively deeper north-south sections of the megaliths. Additionally, divers are often surprised by the presence of blacktip sharks and majestic eaglerays, making for memorable big animal encounters.
As the site offers a range of depths, from shallow sandy areas to deeper megalithic formations, it is suitable for divers of all levels, including freedivers and snorkelers. While no specific best time to visit is mentioned in the provided information, the general diving season in Thailand, particularly for encounters with pelagic species like manta rays and sharks, is typically from November to April. Divers should be prepared for potentially moderate currents, especially in deeper, more exposed areas.
