Racha Noi is the more isolated of the two islands and is a popular dive-site for more experienced divers, as the depths are generally greater and the currents frequently stronger than at its sister island to the North. You will encounter huge underwater boulders that offer a good chance to see manta rays and whale sharks. The northern tip of the island offers an opportunity for a good multilevel dive along a large pinnacle where spotting larger marine life like Reef Sharks and Stingrays is common.
