About this dive site

This dive site, Koh Ngam Noi, is located off the coast of Chumphon, approximately 17 kilometers away. It’s situated 400 meters south of Koh Ngam Yai, a larger sister island. Koh Ngam Noi offers a unique and beautiful experience with its craggy limestone formations and smaller size – it's only about a third of Koh Ngam Yai’s expanse. The coastline features wooden huts nestled amongst the rocks, alongside bamboo poles used to support bird nests. A notable feature is the southern area, where rock formations create natural swim-throughs, providing excellent opportunities for exploration. Divers often find themselves clinging to these rocks in search of various nudibranch species. Expect to encounter schools of Snappers, Jacks, and Yellowtail barracuda in the waters surrounding the island. Blue spotted stingrays can also be seen near sandy areas. The dive site presents a captivating blend of natural beauty and underwater interest.
