Boulders City
(Similan Island 3)

Overview

Large granite rock formations. Boulders City is one of the most distinctive underwater landscapes in Similan. Located on the southeast side of Island 3, it features massive granite rocks scattered on the sandy seabed, resembling an underwater "stone city." Each rock formation creates walls, narrow passages, crevices, and swimming paths, making the dive interesting throughout. The rock formations are also teeming with soft corals, sea whips, and sea fans, which are especially beautiful when there are currents. Due to its relatively deep depths and exposure to currents, it is suitable for experienced divers with good buoyancy control.
