The 2 Rok Islands – Koh Rok Nai and Koh Rok Nok – are tiny paradises 30 km south of Koh Lanta. Small, rugged and mostly unspoilt, they are home to an impressive coral reef system, pristine white-sand beaches, a small ranger’s station, a restaurant and very little else. While there is some accommodation available so that you can stay on the island, this is mostly in the form of tents and a few bungalows.
As part of the Mu Loh Lanta Marine National Park, the Koh Rok Islands have a thriving underwater ecosystem, where divers and snorkelers can encounter sea turtles, moray eels and black-tip reef sharks. On land, on Rok Nai, the beautiful Koh Rok Waterfall is well worth seeing.
