This dive site, Ko Ngam Yai, is one of the two Ngarm islands situated approximately 16km off the coast of Chumphon, Thailand. It is a well-regarded dive site, especially famous within the Chumphon region, known for its accessible depths and vibrant marine life. While no specific history or navigation details are provided in the description, its popularity suggests a well-established and easily navigable underwater environment, likely centered around its coral reefs.
Underwater, divers and snorkelers can expect to encounter a delightful array of marine species. The site is home to lovely triggerfish, fascinating puffer fish, elusive stingrays, camouflaged flounders, and colorful dragonets. The healthy hard corals form a thriving reef ecosystem, which in turn attracts various schools of fish, contributing to the site's lively and picturesque underwater scenery.
The best time to visit Ko Ngam Yai for diving and snorkeling generally aligns with Thailand's dry season, typically from November to May, when water conditions are usually optimal for visibility and calm seas. The shallow average depth of 7 meters makes it particularly appealing for freedivers and snorkelers to explore its rich ecosystem. Divers should be aware of the presence of bird nests on the island, which means going ashore is restricted.
