Koh Rok Nok Island is among the 15 islands forming Koh Lanta archipelago, located off mainland Thailand's east coast. These islands are all part of Mu Ko Lanta National Park (protected marine area). The twin islands Ko Rok are some of Andaman Sea's best snorkelling locations.
The name Ko Rok refers to Ko Rok Nai (closer to mainland) and Ko Rok Nok, both located approx 30 km (19 ml) south of Ko Lanta and 12-20 km (8-12 ml) west of the islands Muk, Kradan and Ngai. The twin islands are rugged, roughly same sized, only 250 m (820 ft) apart, with corals covering the channel in between.
Some snorkelling sites boast names like "Seafan Garden" and "Bermuda Ridge", but it all blends together into an impressive reef system which spans over a square mile. Visibility is great and some of the coral retained its colour regardless of the bleaching in the past. Pufferfish, angelfish and anemones are among the thriving marine life commonly seen. A sea turtle, sea snake, moray eel or even black-tip shark may also be seen.
While Koh Rok Nok Island is completely untouched, Rok Nai features a restaurant, small ranger's station and accommodation zone back from the 500m-long Ko Rok Beach.
