About this site
The dive site near Mannai Island offers vibrant coral gardens teeming with tropical fish, including butterflyfish and angelfish. Gentle currents make it ideal for beginners, while deeper sections reveal occasional reef sharks. Visibility often exceeds 15 meters, with sandy patches hosting garden eels. The sloping reef transitions to boulders at 18 meters, attracting larger pelagics. Water temperatures stay warm year-round, averaging 28°C. Night dives reveal octopus and crustaceans. Accessible by short boat ride from Rayong, it's a peaceful alternative to busier Thai sites.
