Three-Tank Lana’i: Caverns, Drift Lines and Open-Ocean Encounters
A 7.5-hour private, three-tank scuba expedition around Lana’i that visits the Cathedrals, Menpachi and Kaumalapau—useful for planning logistics, certification requirements and what to bring.
Three-Tank Lana’i: Caverns, Drift Lines and Open-Ocean Encounters.
Set off from Māʻalaea for a private, three-tank run around Lana’i that pairs bucket‑list cavern dives with lesser‑known swim‑throughs and a cliff‑lined drift outside Kaumalapau. The full‑day outing is designed to maximize chances of pelagic encounters and dolphin sightings while allowing the dive plan to be tailored to your group’s abilities.
Highlights
Outing Highlights
Cathedrals & Submerged Architecture
The Cathedrals on Lana’i are a primary bucket‑list objective on this itinerary, offering dramatic caverns and passages that define the archipelago’s underwater topography.
Menpachi’s Swim‑Throughs and Kaumalapau Drift
Less heralded sites such as Menpachi feature multiple swim‑throughs and arches, while Kaumalapau (also called Barge Harbor) is a western‑coast drift dive set among steep cliffs.
Pelagics on the Edge
Because these dives sit close to deep water, the expedition increases opportunities to encounter pelagic species and carries a strong chance of dolphin sightings.
