This dive site, Marina Bay, is situated on the western side of Racha Noi's North Island, offering a unique underwater exploration. Divers typically enter the bay and proceed south, where they encounter an impressive landscape characterized by 'rumbling megaliths' and overlapping boulders. The site is famous for its natural swim-throughs, which are dotted among these rock formations, providing an adventurous and stimulating experience for divers. No specific history or story is mentioned beyond its natural formation.
Marina Bay boasts a rich diversity of marine life, with manta rays being a significant highlight, frequently observed and considered the best part of the dive. Within the dimly lit swim-throughs and around the boulders, divers can spot various macro-organisms including fish, shrimps, crabs, and nudibranchs. Molluscs such as octopuses, often mimicking rocks, and barnacles, also add to the site's biological tapestry.
The best time to visit Marina Bay is when manta rays are most active, though specific months are not provided. The site's shallow average depth of 8 meters makes it highly suitable for both beginner divers and freedivers looking to enjoy the swim-throughs and search for macro life. Its appeal to a wide range of underwater enthusiasts makes it a popular destination for those exploring the waters of Racha Noi.
