Dive-site story
Located off the coast of Sattahip in the upper Gulf of Thailand, Samaesan offers an energetic mix of historical shipwrecks and rocky island reefs. The area is famous for the Hardeep, a sunken World War II cargo vessel covered in soft corals and sponges. Diver traffic here often contends with notable tidal flow moving between the offshore islands, creating nutrient-rich feeding grounds across the granite boulders and sloping sand bottoms.
