Koh Lanta is the closest island to the famous dive sites Hin Daeng (Red Rock) and Hin Muang (Purple Rock). These dive sites are known as one of the best dive sites in Thailand. Manta rays and Whale sharks are regularly seen here from February through April. 

There are no dive sites and interesting snorkeling spots close to Lanta. You need to go on a boat trip to reach them, but it's worth the effort. The Andaman sea contains many different marine life species and you can expect to see a lot of them. For sure you are going to see different types of clownfish, butterflyfish, damselfishes, fusiliers, groupers, snappers and trevallies. Futhermore you have a realistic chance to see turtles, the yellow boxfish, an octopus, the scribbled filefish, the giant moray, nudibranchs, the black spotted puffer, lion fish and the titan triggerfish.
