Koh thian - Koh rang national park

Koh Thian in the Koh Rang National Park is a beginner-friendly dive site in the eastern Gulf of Thailand, where the protected waters around this small island host healthy reef systems accessible to divers of all experience levels. With a maximum depth of fifteen meters, the site provides easy conditions and reliable marine encounters within the conservation zone of the national marine park. The reef around Koh Thian features coral growth on rocky substrate, with the national park's protection ensuring above-average health and diversity. Hard corals form the structural foundation, while soft corals and anemones add movement and color. The sheltered conditions and moderate depth make the site comfortable for newer divers while the marine quality impresses experienced visitors. Fish life benefits from the park's restrictions on fishing, with populations healthier and more abundant than at unprotected sites. Schools of fusiliers and snappers provide mid-water spectacle, while reef species populate the coral gardens. Turtles visit the reef to feed, and the macro life includes nudibranchs and various crustaceans. Koh Thian provides accessible diving in a protected marine environment that demonstrates the value of conservation. The combination of easy conditions, healthy reef, and the national park setting creates a thoroughly pleasant dive experience in the Koh Chang archipelago.
