This dive site, Nam Chai Bay, also known as Mooring Bay, is a popular check dive location within Thailand's renowned Similan Islands. It features a gently sloping reef that gradually transitions to a sandy bottom at depths of 20-25 meters. The topography is characterized by impressive granite boulders and extensive, healthy hard coral formations, providing an easy and enjoyable navigation experience ideal for divers re-familiarizing themselves with their equipment and buoyancy.
The bay is a vibrant ecosystem teeming with marine life. Divers can expect to encounter abundant reef fish, find turtles resting on the sandy patches, and explore beautiful anemone gardens. Occasional sightings of blacktip reef sharks add to the excitement, making it a diverse site for both macro and wide-angle photographic opportunities.
The best time to visit Nam Chai Bay is typically during the Similan Islands' diving season from November to May, when sea conditions are generally calm and visibility is excellent. Its relatively shallow maximum depth and rich biodiversity make it an excellent spot for beginner divers, underwater photographers, and freedivers seeking a relaxed and rewarding experience.
