One of the best diving sites in the Racha Islands, the northern tip of Racha Noi offers dramatic underwater scenery. Despite this being a relatively shallow dive site (the dive starts at around 5 metres and goes down to around 35 metres), very strong currents mean only the most advanced and experienced divers should dive here. This area is renowned for large fish and the coral is outstanding. The islands are 35 kilometres south of Phuket and you will need to charter a boat to get there.
