This dive site, Koh Mat Wai Yai, is situated within the picturesque Mu Koh Chumphon National Park in Thailand. The island itself is home to a bird nest concession, meaning divers cannot land ashore, making it exclusively a boat-accessed dive location. The underwater topography is generally shallow and easy to navigate, primarily consisting of reef formations surrounding the island.
The marine life here is remarkably diverse, showcasing a 'fish that symbolizes the love of the sea,' alongside fascinating macro creatures such as seahorses, pipe fish, and razor fish. Larger species include barracuda and graceful sea turtles. The reef is also bustling with a variety of colorful butterfly fish, angel fish, and gobies, complemented by the presence of squid.
Koh Mat Wai Yai is a fantastic destination for all levels of divers, including snorkelers and freedivers, due to its shallow depths. The abundance of small, interesting creatures makes it particularly rewarding for macro photography enthusiasts. The best time to visit aligns with Thailand's typical dry season, offering optimal visibility and calm conditions, though diving is possible year-round.
