56 miles from Ao Chalong
These islands were the location for filming of the French version of the popular Survivor series. They offer a semi-sheltered anchorage during both seasons. Anchor in 12-15 metres in the eastern approach to the channel on the east side of Koh Rok Nok or in 3-6 metres on the north end, depending on the ground swell; anchorage (B) [7°12.989N, 99°3.617E] is the most secure.
The channel is deeper (3 metres) closest to Koh Rok Nok and can be navigated with care and a good lookout. The Marine Department orange mooring buoys in the channel are sometimes OK for yachts but should be inspected first. The white buoys off the fringing reef to the east of Koh Rok Nok are too shallow and flimsy, only suitable for speedboats and longtails. The water is clear with a sandy bottom and there is great snorkelling and diving around the islands.
The National Park headquarters, a small restaurant and camp ground is on the south side of Koh Rok Nai. Barbeques are prohibited on the beaches. A fee of 500 baht per person per day is applicable and you will probably be visited by the Marine Department RIB once you have anchored. On the north beach on Koh Rok Nok is an animist temple stacked with wooden phallic effigies created by local fishermen for good luck?
Hin Daeng, 12 miles west-southwest 7°09.126N, 98°49.297E, is a pinnacle rising out of 70 metres depth and was a spectacular dive site until illegal dynamite fishing incidents.
