Manta Sighting Guarantee! (until 2020/12/31)

On the rare occasion where zero manta rays are sighted on your tour, Sea Quest invites you to come back out on another night at no additional cost to you, or on a confirmed Captain Cook Express afternoon snorkel tour at no additional charge. Non-transferable. No refunds given.

- Based on space availability.
- This non-transferable offer allows you to reschedule your tour for free; it does not entitle you to a refund.

The light from the hotels near Keauhou Bay has created a large population of plankton in the area, which in turn attracts nocturnal manta rays to the area every night to feed on the abundant plankton. This adventure takes you to manta feeding grounds on a snorkeling excursion like no other! Just minutes away from the shore, this tour wastes no time in getting you into the water and among the rays. You don't have to worry about the dark, as the area is brightly lit, even underwater! With all your gear and snorkeling equipment provided, all you have to do is show up to this awesome spectacle!
