Planning a trip?
Hotels, dive operators, gear, and how to get here are on the Blue Corner location page.
Overview
Four vertical shafts in the reef table that open into a single cavern. Drop through the holes at 10 m, exit at 30+ m through the cavern window, then drift to Blue Corner. Beam-shafts of light through the openings make it one of the most photographed dives in the Pacific.
Briefing note
Most operators run Blue Holes into a Blue Corner drift — single tank, two iconic sites.

Sources & methodology
How we summarise this
We aggregate confirmed occurrence records from GBIF and OBIS within a fixed radius of each dive site. Occurrence records confirm presence and reveal seasonality clustering, but they DO NOT measure per-dive probability — there is no eligible-effort denominator. We deliberately do not publish a numeric '% chance of sighting' from this data.
