About Catalina Wreck
Catalina Wreck is Biak's signature wreck dive, with an intact World War II-era Catalina seaplane resting offshore and giving divers one of the clearest history-plus-reef dives. The site is usually done by boat around a clearly shaped wreck, so trim and buoyancy matter more than a long swim. On calm days the water is clear enough to read the airframe, coral growth, and schooling fish around the structure. It suits divers who are comfortable with a deeper profile and want a compact wreck rather than a broad reef.

Local Intel For Catalina Wreck
Community notes to help plan your visit.
Scuba Diving
Best as a controlled wreck dive around a compact airframe. Keep trim tight, plan gas for a deeper profile, and move slowly so the wreck and coral growth stay protected.
Freediving
Not a practical freedive target for the wreck itself; the profile is too deep for meaningful access without scuba.
Snorkeling
Snorkeling may work as a surface visit on the boat, but the wreck itself is too deep to snorkel in any useful way.
