About this dive site
This dive site, Koh Ngam Yai, is a renowned location within the Gulf of Thailand. Situated 400 meters north of its smaller sister island, Koh Ngam Noi, it boasts a unique landscape characterized by limestone formations with sparse vegetation and strikingly natural rock structures. The surrounding waters are rich in colorful coral reefs teeming with diverse fish species. Diving is primarily conducted on the east side of the island, and the dive area is marked with buoys. This location offers a favorable experience for both divers and snorkelers due to typically mild currents and visibility that can reach up to 20 meters.
