Dive beneath the starlit waters off Kona’s coast for a two-hour guided night snorkeling adventure among giant manta rays. Learn how Hawaii’s unique ocean conditions create a mesmerizing encounter with these gentle giants.
As darkness descends upon the Kona Coast of Hawaii, the ocean transforms into a living stage where giant manta rays glide with effortless grace. This night snorkeling tour offers an up-close encounter with these extraordinary creatures, whose immense wingspans—sometimes exceeding 20 feet—cast shadowy silhouettes against the illuminated waters. Guided by expert hands, adventurers don wetsuits and snorkel gear before slipping into the steady Pacific current, holding fast to a buoyant bar anchored to a raft outfitted with powerful LED lights. These lights lure plankton, the manta rays’ primary food, which in turn draws the graceful predators into a mesmerizing feeding dance.

Post-snorkel temperatures can get chilly—pack a towel and warm layers to stay comfortable on the boat ride back.
Check in at least 15 minutes before departure at Honokohau Harbor to ensure a smooth boarding process.
Protect the marine ecosystem by applying reef-safe sunscreen before your adventure, though avoid applying it right before entering the water at night.
Grip the raft bar to stay steady in the current and keep position under the LED lights to view the manta rays feeding.
The Kona coast has long been a fishing ground for native Hawaiians, with manta rays traditionally respected as important ocean inhabitants.
