Similan Islands Thailands Best Islands
Koh Bon is a solitary limestone island 12 miles north-northeast of Koh Similan. Unlike the Similan Islands, Koh Bon is made of limestone and has a completely different geological past.
Due to this fact, the marine lifes there thrives in a different way compared to the other islands. The limestone is a perfect substrate for soft corals and rough underwater features make Koh Bon famous for schools of bigger predator fish and regular visits of marine megafauna like giant manta rays and whale sharks.
