Manta Discovery Tour

Quick Details


Manta Discovery…at night!

Our newest tour and the only tour of it’s kind on the east side of Hawaii’s Big Island. Join us for this rare and exhilarating experience – the Night Manta Discovery Tour. Snorkel around a lighted raft while the mantas come to feed on an accumulation of plankton just offshore.

Our in-water guides help find mantas feeding at the surface and ensure the safety and comfort of our guests. Mantas are very gentle – no teeth, stingers or barbs.

They are simply big and beautiful with wingspans that can exceed 15-feet in width! The experience of seeing these massive gentle creatures in the wild is exhilarating and makes for an incredible adventure of a lifetime!


Snorkelers must be at least 8 years, know how to swim, have snorkeling experience, be physically fit, with no medical conditions and comfortable being on a boat at night understand and speaking English for safety reasons.
