Pulau Hantu was where Malay warriors once dueled to the death and their ghosts are said to wonder the island.Despite its forbidding name, Pulau Hantu is a favourite haunt for fishing, scuba diving and snorkeling enthusiasts because of its sheltered beaches, swimming lagoons and inviting waters. The islands are also popular with campers and day-trippers who prefer a unique outdoor experience.
Pulau Hantu has rich reefs despite its proximity to Pulau Bukom’s refineries. A wide variety of corals can be found on Pulau Hantu, and mushroom corals are particularly abundant in the waters surrounding the islands. Common sea life that can also be found include the clown fish or anemonefish, damselfishes, wrasses and angelfish. The rare giant clam and the seahorse can sometimes be seen. There is a small patch of mangroves between Pulau Hantu Kecil and Pulau Hantu Besar, where native seashore plants also line their beaches.
