Best time to dive
May to September
What you might see
- Eagle rayLikely
- Manta rayLikely
- Whale sharkPossible
Sightings are seasonal probabilities, not promises - even in peak season nature does its own thing.
Certification & difficulty
Advanced Open Water - advanced conditions (currents/depth); dive within your training.
Snorkelling
Not a snorkel site - Not at the pinnacle itself (deep wall dive); ride-along/snorkeler fares are offered on the same charter, and separate snorkel tours visit the calmer interior of Lehua Crater
Safety notes
Long open-ocean channel crossing with swells/seasickness, remote location far from medical/chamber support, strong current/drift, depth exposure on a wall dropping to 300 ft
Permits & fees
No diver-specific permit or fee; Lehua Rock (the actual dive site) is a state/federal seabird sanctuary managed by Hawaii DLNR and the US Coast Guard, distinct from the privately-owned Niihau island - no Robinson family permission needed for diving the surrounding waters
Permits and operators change - confirm before booking.
Location
Nearest hub: Niihau (via Kauai charter)
