The iconic deep-blue sinkhole.
The dive
The 300 m-wide sinkhole is a deep, dark descent past ancient stalactites — a bucket-list dive best framed by the vivid atoll walls of Lighthouse Reef around it.
When to go
Diveable much of the year; April–June is calmest and clearest. The Hole is one deep dive — the atoll reefs around it are the real richness.
