潜点: Koh Bon — West Ridge

关于 Koh Bon — West Ridge

Koh Bon West Ridge, nestled in Thailand's Similan National Park, is a renowned dive site celebrated for its stunning topography and abundant marine life. This uninhabited limestone island, approximately 20 kilometers northwest of the main Similan group, features a horseshoe shape with a distinctive hole cut through by strong waves. The West Ridge itself extends out from the western side of the island. Visible are impressive rock formations, sheer walls, and a variety of colorful soft corals, some forming unique mushroom-shaped bommies and sea fans that sway with the current. The general underwater scenery is well-preserved. It is a cleaning station for manta rays, especially during January to April, when they come to feed on plankton and be cleaned by smaller reef fish. Other frequent sightings include barracudas, tunas, groupers, eagle rays, stingrays, leopard sharks, and various reef fish and invertebrates. The West Ridge features a steep, coral-covered slope on its western side and a dramatic wall on its northern side, both descending to significant depths. While the ridge offers shelter for macrolife like nudibranchs, moray eels, and shrimp, the main draw is the pelagic action, with schools of trevally, barracuda, and rainbow runners often present. The nutrient-rich currents that flow along the ridge are a magnet for larger marine species. Visibility typically ranges from 20 to 30 meters, with comfortable water temperatures between 28 and 30 degrees Celsius. Diving here typically involves a drift along the ridge, often spent hovering, observing the spectacular marine life. Due to its depths and currents, this site is best suited for intermediate to advanced divers. Day trips to Koh Bon are a popular option, with some operators offering two-dive excursions. Conditions are usually good, allowing for clear views of the vibrant underwater world, making it a highlight for divers exploring the Similan National Park area.
