Manta Ray Night Snorkel
by Jack's Diving Locker

Manta rays are filter feeders and feed on plankton attracted to light. They have very large mouths, but no sharp teeth. Manta rays do not have tail stingers.

This is a thrilling experience for those who seek adventure!

Manta Guarantee: While we see mantas about 85% of the time, they are wild animals and their appearance is beyond our control.  If you don’t see a manta on your night out, you can go again on another night on a space available, standby basis.  Keep in mind that these spaces may be very limited, especially during the busiest times of the year.  However, the offer never expires but is non-transferable and has no refund or cash value.



Join the knowledgeable and friendly crew of Jack’s Diving Locker for a night to remember on the world famous Manta Night Snorkel. Take a boat ride in the late afternoon along the Kona coast to the manta viewing site. Slip into the water with your snorkel guide and float above majestic manta rays as they somersault, glide, and pivot in the light below.

MANTA TOUR PARTICIPANT GUIDELINES OBSERVE ONLY: No touching. Resist the urge to “pet” the mantas. This will rub off their protective mucus coating. Do not chase, grab, or try to take a ride on the mantas. This doesn’t benefit the animal in anyway.

DIVER POSITION: Divers must stay on or near the sand, rubble or boulder bottom. An open water column is necessary for the mantas to maneuver. Avoid contact with coral, sea urchins, or other marine life. Form a semi-circle with your group.

SNORKELER POSITION: Snorkelers must stay on the surface and keep legs horizontal. Do not dive down into the water column.

LIGHTS: Divers please shine lights up into the water column to attract plankton. Snorkelers please shine lights down.

BUBBLES: Divers try to time your breathing so that you don’t blow bubbles up into the manta if it’s passes over your head.

TAKING PHOTOS or VIDEO: When taking underwater photos or video, be considerate of people and mantas. Minimize your equipment in the water column and let the mantas come to you.

These guidelines were first established in 1993 by manta dive operators in Kona, Hawaii. Reviewed again in 2013 by manta tour operators (dive and snorkel operators).


When can I fly or drive to altitude? 
For single dives a minimum surface interval of 12 hours is suggested before flying. If you have been doing multiple days of multiple dives, PADI recommends a minimum surface interval of 18 to 24 hours.  We also strongly recommend that you do not plan to drive to the volcano, Waimea or Hilo, take a helicopter tour or stargaze on the top of Mauna Kea the same day that you dive.  Following these recommendations reduces DCS risk but does not guarantee that a diver will avoid DCS.
