Underwater reef at Kona Coast
Stable

Kona Coast

United States · Hawaii

Kona on the Big Island of Hawai'i is one of the world's best manta dives — the Kona manta night dive, where mantas feed on plankton attracted by divers' lights — plus pelagic blackwater diving and reef sites along the leeward coast.

How this reef is doing

How we measure this

Reef state

Stable

Manta night dive and blackwater are both unchanged — those don't depend on coral. Day diving over reef shows recovery in patches. Worth going for the pelagic experiences alone.

What divers say

A manta with a 4m wingspan barrel rolling six inches from my mask in a halo of light — the Kona night dive is on the bucket list for a reason.

Good to know

Blackwater

Offshore drift in 3,000m of water at night, looking at planktonic critters. Once-in-a-life experience.
