Perhentian Islands is one of the fifteen most beautiful paradise islands to visit in Asia. It is an archipelago of islands and is believed to be the most laid back found in the area. The islands have hidden coves, beautiful sandy beaches and crystal clear waters that are perfect for diving and snorkeling.

The Perhentian Islands comprise two main islands, Greater Perhentian and Lesser Perhentian. There is an archipelago of smaller, uninhabited islands. Nature tourism is the main economic activity for the two main islands. The islands are fringed with palm trees, the beach is covered with white coral sand and the sea is turquoise blue.

There are at least twenty-two dive sites at Perhentian Islands, with average depth ranging from 1 metre to 22 metres. Parrotfish, stingray, yellowtail, boxfish, puffer fish and a variety of sea cucumber are found in shallower waters while shovelnose ray shark, barracuda, batfish, snapper, wrasse, jack fish, stingray and grouper are found in deeper waters.

The Turtle Conservation Project at Perhentian Islands helps to conserve sea turtles by identifying the turtles using snorkel photo identification and night beach turtle patrol. The project collects scientific data by literally snorkelling and snapping photos of turtles, which are used to identify individual turtles and their movements.
