Every year whale sharks follow a path between Malaysia past Koh Ha, Hin Daeng and the Bidas to the Similan Islands. Normally divers see them in these area’s from end of November until end of February. This year though we have had almost every day sightings at Koh Ha, Hin Daeng , Bidas and Koh Rok for the last 2 weeks already. In actuality we have had whalesharks pretty much most of our green season.
