Terumbu Tiga / Three Rocks is a signature Perhentian boulder site made of three huge rock towers and smaller blocks, with caverns, swim-throughs, soft corals, and a strong mix of reef fish. It suits divers who want structure and overhead-style passages more than a flat reef, and it rewards slow, careful movement across the rocks.
Conservative baseline from public research. No community dives logged yet.
Depth range, seasonality, and planning context.
Reported Depth
10m - 25m
Depth Note
The rock tops are shallow and the useful dive band stays around the boulder faces and swim-throughs.
Best Season
March to April, with the broader dry season also being a good fit.
Typical Conditions
Large boulders, swim-throughs, soft coral, and a route that rewards calm water and slow movement.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Treat the swim-throughs as overhead environments, and keep your route, gas, and exit plan conservative.
Access Restrictions
The caverns and swim-throughs call for certification and disciplined buoyancy, so this is not a casual first-dive site.
Legal Notes
Stay within your certification and follow local dive-operator guidance through the overhead sections.
Community notes to help plan your visit.
Scuba Diving
The main attraction is the maze of boulders, swim-throughs, and sheltered pockets that make it a buoyancy-control dive.
Freediving
Not ideal for freediving because the site is built around boulders, caverns, and swim-throughs.
Snorkeling
Snorkeling can work only on the calmest shallows, but the site is much better as a scuba dive.
