Blackwater diving - a specialized night dive over deep open ocean (not a reef), observing rarely-seen deep-sea pelagic creatures that rise toward the surface after dark
Available as a shared or fully private charter
Blackwater diving is a niche, advanced-interest category: divers descend on a line into open, very deep water at night (no reef or bottom in sight), observing bizarre and rarely-seen deep-sea larval and pelagic creatures that migrate upward after dark. Kona is one of the world's most established blackwater diving destinations due to the steep drop-off just offshore.

Tripreviewall's Take
A genuinely unique, advanced-interest dive - not for casual or nervous divers, but remarkable for the right audience.
Good for
Experienced divers with strong buoyancy control and comfort with open-water, no-visible-bottom conditions
Underwater photographers interested in rare deep-sea macro life
Worth knowing
This is genuinely different from a normal night dive - no reef, no bottom in sight, floating over very deep open ocean on a line
Not recommended for anyone uneasy with open-water disorientation or without solid buoyancy control
Private charter costs more but offers a smaller, more personalized group for what is already a niche, specialized dive

Google Maps — Summarized by Our Team
Kona is widely regarded within the international dive community as one of the best and most accessible blackwater diving locations in the world, owing to the unusually steep underwater drop-off close to the Kona coastline that brings deep-sea conditions within a short boat ride.
