West of Eden about the site
West of Eden is defined by massive granite boulders that form a series of impressive canyons, creating a unique topography. As you descend, these formations transition into walls blanketed with soft corals and giant gorgonians, painting a colourful underwater landscape. The site is situated off the west side of Koh Pa-Yu, Similan Island #7, offering varied underwater scenery from its shallow reef to a deeper sand slope.
The dive here often involves navigating through these canyons, where light filters in, highlighting the diverse invertebrate life. The deeper sections of the site feature a sand slope that extends down to approximately 35 to 40 meters. This transition from hard rock formations to soft debris areas creates distinct habitats, attracting different species of marine life seeking refuge or hunting grounds.
Along the walls and within the rock formations, the site hosts a rich macro environment. Keep an eye out for Ribbon Eels (Rhinomuraena quaesita) emerging from crevices and the well-camouflaged Frogfish (Antennariidae) blending into the coral. Ghost Pipefish (Solenostomidae) are also found here, often swaying gently alongside feather stars, providing excellent opportunities for focused observation.
Beyond the macro life, the topography at West of Eden encourages pelagic activity, especially during stronger currents. Schools of Bluefin Trevally (Carangoides ferdau) and Giant Trevally (Caranx ignobilis) are common, along with Fusiliers (Caesionidae), often seen darting through the water column. White-tip Reef Sharks (Triaenodon obesus) cruise the perimeters, particularly when the water flow increases.
The shallow fringing reef offers a different experience, dominated by stacked granite boulders and extensive fields of hard corals. This area is vibrant with numerous reef fish and studded with a variety of soft corals, sea fans, and crinoids, creating a thriving ecosystem. It's a prime spot for new divers to acclimate to the environment or for experienced divers to extend their bottom time searching for hiding creatures.
Visibility at West of Eden typically ranges between 15 and 30 meters, often allowing for clear views of the expansive canyons and walls. While the current here is generally moderate, it can intensify, particularly during tide changes. This site is also home to a variety of crustacean life, including Crabs, Shrimps, and Lobsters, often found tucked into the many rock fissures and under ledges.
