'Rok Islands’ or Koh Rok glistening turquoise is so crystal clear that one can easily see colorful coral reefs down under, inviting us to take a plunge and explore an intimate, deep-sea experience that is just perfect for snorkeling. Bordering Krabi and Trang seas, the island was previously difficult to travel to and the result is the well-preserved, unspoiled nature. Rok Islands contains two islands separated by a narrow waterway: Rok Nok and Rok Nai.

The center of Koh Rok having beautiful white and very firm sandy beach stretching from the head to the tip of the island of crystal clear water. Just wear the snorkel and dive to see the undersea world of the fertile coral reefs of many species, groups of fish and the giant clam. Behind Koh Rok is the trail to Thalu Bay of stone beach all over the island with the way up to Pha Samet Daeng Viewpoint to see the scenery farther to Koh Lanta.

The only human’s interference on Koh Rok Nak is the Ranger Station of Lanta Archipelago National Park that serves as a beachside residential area, restaurants and camping spot at Man Sai Bay. It is also where tents and bedding gears are available for rents. The quiet Man Sai Bay is also home to land hermit crabs, which allows visitors to engage in a contribution activity, “Land Hermit Crab’s Home” in which participants will leave empty shells on the beach so the crabs can make their homes out of them.

This is a good site at all depths. The diving is around the southern coast, eading slightly northeast. This is also a reasonable snorkelling site, since conditions are almost always calm. The reef slopes gently and there are lots of hard corals, including brain and table staghorn, and many barrel sponges. The reef fish are reasonably plenteous; they include banner fish, large schools of moorish idols, a good variety of anemonefish and on occassion, turtles. Away for the reef, large barracuda, tuna and jacks pass by.
