This dive site, known as Koh Bon, The Bay, is located on an uplifted limestone island approximately 50 km west of Khao Lak and 20 km north of the renowned Similan Islands. It features a long, narrow ridge point on the island's west side, characterized by a sloping wall adorned with hard coral landscapes. While no specific history is provided, its geological formation and location contribute to its vibrant ecosystem. Divers typically navigate along the wall, exploring the various crevices and coral formations.
The marine life at Koh Bon is diverse and exciting. Divers can expect to encounter a variety of macro life such as nudibranchs, octopus, and moray eels, showcasing the site's rich biodiversity. The area is particularly famous for its larger inhabitants, with regular sightings of majestic manta rays and the awe-inspiring whale sharks, especially by the bay area. Hard corals form the backbone of the underwater landscape, providing shelter and sustenance for numerous reef fish.
The best time to visit Koh Bon, aligning with the diving season for the Similan and Surin Islands, is typically from November to April when conditions are generally calm and visibility is excellent. For divers, be prepared for variable currents, especially around the ridge point, which can be moderate to strong and enhance the drift diving experience. Freedivers will also find the site suitable, with an average depth of 11 meters and a maximum of 22 meters, allowing for exploration of the wall and encounters with pelagics closer to the surface.
