This dive site, known as Chinese Wall, is located on the south tip of Island 4 within the Similan Islands. It earns its name from its remarkably long, continuous rock wall formation that stretches along the seabed. While currents can be encountered at deeper sections, the shallows provide natural shelters among the rocks, allowing divers to escape stronger flows. The site primarily features this impressive wall structure, offering a unique underwater topography.
The marine life here is characteristic of the Andaman Sea, with a strong presence of smaller creatures ideal for macro enthusiasts. Divers can anticipate encountering various reef fish, colorful crustaceans, and potentially nudibranchs. Venturing to deeper parts of the wall increases the chances of spotting larger pelagic species, including different types of rays and reef sharks, making it a dynamic environment for diverse animal encounters.
The best time to visit the Similan Islands, and consequently Chinese Wall, is generally from November to April when the weather is dry and seas are calm, offering optimal diving conditions. This site is suitable for both scuba divers and freedivers, particularly in the shallower, current-protected areas. Its varied depths and potential for both small and large marine life provide a rewarding experience, though divers should be mindful of potential currents at deeper levels and plan their dives accordingly.
