Ni'ihau
Monolithic lava formations provide for an array of habitats. Ni’ihau has the most amazing labyrinth network of lava tubes in the state. The mouths of the tubes are 100 feet wide and extend back 150 feet+, only to drop into another passageway. Huge underwater erosional sea caves and arches change the colors around you. This topography is sure to blow your mind. It is the only dive destination in the world where you have an excellent chance to swim with the most endangered marine mammals in U.S. waters, the Hawaiian monk seal. Boat's leave from Kauai, and it's usually an all day 3-tank trip to get here.
