Perhentian diving guide
Two islands, Besar and Kecil, popular for affordable Open Water courses, turtles and easy reef diving.
About diving at Perhentian
The Perhentian Islands — Besar ('big') and Kecil ('small') — sit in the Terengganu Marine Park and are one of Malaysia's most popular places to learn to dive. Kecil has a backpacker buzz around Long Beach, while Besar is calmer with more family resorts.
Over 20 dive sites are within a short boat ride, mixing gentle coral slopes, rocky pinnacles and a sunken cargo ship. Turtles are seen so often that they become part of everyday diving here.
What makes Perhentian special
- Temple of the Sea (Tokong Laut)A pinnacle rising from deeper water, covered in soft corals and fish. It can have current and suits divers with some experience.
- The Sugar WreckA cargo ship that sank near the islands, now a popular wreck dive full of fish life, at a depth suited to Advanced-level divers.
- Shark PointKnown for blacktip reef sharks patrolling the reef.
- Turtle-filled shallowsGreen and hawksbill turtles are regular companions on Perhentian reefs and even while snorkelling.
