Basak
One of the top dive sites in Zamboanguita: a large coral reef with sandy patches, where we quite often meet pelagics such as whale sharks and manta rays.

Basak (also spelt Basac) is one of the top dive sites in Zamboanguita, just south of Dauin. It has a huge coral reef, broken up by patches of sand, and it lies inside a marine sanctuary.
It is also one of the places where we quite often encounter pelagics, including whale sharks and manta rays. Sightings of big animals are never guaranteed, but it is always worth keeping one eye on the blue.
The dive
The maximum depth is between 18 and 24 metres. The reef is large enough that no two dives are the same, and the sandy patches between the coral add variety.
What you might see
- A large coral reef with plenty of reef fish
- Sandy patches worth checking for smaller life
- Whale sharks and manta rays, with luck
When to dive Basak
Basak can be dived all year, and the water stays between about 25 and 29°C. Pelagic sightings are unpredictable, so ask our team what has been seen recently. See when to dive Dauin.
Who it suits
Reef lovers, and anyone hoping for a big-animal encounter. It is a good contrast to the macro sites along the Dauin coast.
Our tip
Look up from the reef every few minutes. Big animals tend to pass by in the blue, not over the coral.
Good to know
- Basak is a marine sanctuary. The standard sanctuary fee is included in our dive price; with a camera, add PHP 50 per dive.
- If you meet a whale shark or manta, keep your distance, don’t touch, and never chase it.
- For more coral reefs, try Dauin South or a day at Apo Island.
