This dive site, Koh Bon North Reef, offers a relaxed and accessible diving experience, particularly suitable for beginners. The site features a gently sloping reef primarily composed of hard corals, which gradually gives way to a sandy bottom at depths between 10 to 30 meters. Underwater navigation is straightforward, following the reef slope. While there isn't a specific historical event tied directly to the reef, Koh Bon is a renowned island within the Similan Islands National Park, famous for its rich biodiversity.
Divers can expect to encounter an abundance of reef fish, including impressive barracudas and various species of moray eels. The vibrant hard coral formations dominate the landscape, providing habitat for numerous smaller reef inhabitants. Although not its primary draw for larger pelagics, occasional glimpses of sharks can add excitement to the dive.
The best time to visit Koh Bon, aligning with the Similan Islands season, is typically from November to May when weather conditions are most favorable and marine life is prolific. This site is excellent for those seeking a tranquil dive with good photographic opportunities for both wide-angle reef shots and capturing reef fish. Freedivers will also find the gentle slopes and good visibility appealing for exploring the shallower sections of the reef.
