Hua Chedi Koh Ngam Yai is a buoyed shallow reef south of Koh Ngam Yai that works well as a first dive and buoyancy check. The bottom stays flat and sandy, while sea anemones and coral close enough to the surface keep the site lively. Expect clear water, Indian clownfish, nudibranchs, and triggerfish, with occasional current around the turning point. On calm days, snorkellers can use the reef too.
