Your next stop is Koh Lanta, Koh Phi Phi's laid-back neighbour! Considered one of the best dive spots in all of Thailand, Koh Lanta is very popular with snorkelling enthusiasts. A 27-mile stretch of white, sandy shoreline, lush green mangroves, forests and caves allow for plenty of exploration. You can also explore the island via a moped. Head over to Mu Koh Lanta National Park, which is the biggest attraction on the island. The Park offers a superb wildlife experience and fascinating snorkelling adventures. Also, if you wish to get away from it all and experience a bit of solitude, a short boat ride will take you to uninhabited paradise isles such as Rok Nai and Koh Rok Nok.
