Boulder maze with swim-throughs and rich reef life.
Terumbu Tiga (T3) is a boulder maze of three massive rock stacks and smaller blocks, with channels, swim-throughs and coral-covered slopes that reward careful buoyancy. It is a shore-accessible Perhentian classic for wide-angle scenery, small critters and regular fish action rather than a fast current dive. It is especially good for buoyancy practice and mixed wide-angle or macro sessions.
Site Conditions
Safety Notes
Swim-throughs and tight channels are present; appropriate training, buoyancy control, and awareness are recommended.
Access Restrictions
Overhead swim-throughs mean it suits certified divers with solid buoyancy control.
Legal Notes
Follow local dive rules, marine-park guidance and operator instructions inside overhead sections.
Community notes to help plan your visit.
Scuba Diving
Advanced divers can explore channels and swim-throughs created by stacked boulders.
Freediving
Not a primary freedive target; the overhead sections and structure make it better suited to scuba.
Snorkeling
Casual snorkeling is limited by the boulder maze and depth changes; scuba is the better fit.
