Koh Rok Nai and Koh Rok Nok make up the Rok Islands they are small paradises 30 km south of Koh Lanta Island. Home to an impressive coral reef system, pristine white-sand beaches, a small ranger’s station, a restaurant and not much else. There is some accommodation available on the islands mostly made up of tents and bungalows. Part of the Mu Lo Lanta National park there is a thriving ecosystem, a great spot for scuba diving and snorkelling. There is also the very beautiful Koh Rok waterfall which is definitely worth a visit.
