To confirm
Koh Rok is a pair of uninhabited islets — Rok Nai and Rok Nok — forty kilometres south of Lanta, inside the national park. The channel between them is a few hundred metres wide and holds a coral reef in good condition, which is rare in the region.
The absence of inhabitants explains the water quality: no discharge, no building, and visits limited to day trips. The park closes entirely from mid-May to mid-October for the monsoon, which leaves the reef six months without visitors — and that is part of why it is in the state it is.
Getting there
An hour by speedboat from Saladan, in the north of Lanta. Day trips only.
What the price covers

Rules on site
The park is closed from mid-May to mid-October: no trips run. The park fee is paid in cash to the ranger and is almost never included in the advertised price.
