A Breathtaking evening experience!

If you only have time for one snorkel trip while visiting us here in Kona, Hawaii this is the one to choose. This tour includes an evening snorkeling adventure considered to be the most memorable and best value of any of the island’s numerous snorkel trips.

Board our vessel and take a short cruise to the mouth of Keauhou Bay to swim with and view the manta rays. The manta ray is the largest of the ray family and one of the largest fish in the world, with wing spans up to 12 ft. wide or more.

Due to an abundance of plankton that comes to Keauhou Bay each night after sundown this shallow bay is home to one of the highest concentrations of manta rays in the Hawaiian Islands.  

Imagine. Floating in a dark ocean near the water’s surface holding on to our flotation device outfitted with lights that attract plankton, when giant prehistoric, creatures with wingspans over 12’, glide silently and effortlessly into view from out of the inky dark boundaries of light.
Plankton are attracted by the strong lights that shine directly on the bay from atop the nearby hotel as well as from our flotation boards specially equipped with powerful LED lights. The plankton that is attracted by these lights are feasted on by the manta ray which filter out the plankton by swooping through the water with their mouths wide open. Sometimes as they feed, the manta ray will swim while doing somersaults (barrel rolls) and turning gracefully in the beams of piercing light giving you the most unforgettable snorkel adventure EVER!
Things to know:
  • Guests can expect to spend approximately 45 minutes in the water
  • Masks, snorkels, short sleeve wetsuit tops, hot tea, pool noodles provided
  • Minimum age: 8yrs old
  • Must be comfortable with swimming and snorkeling in the ocean

 (PLEASE NOTE: It is not possible to do “free snorkeling” during the tour because your snorkel and fins can hurt the manta rays. Furthermore, touching them can remove their protective skin coating which can leave them susceptible to infection. Manta rays may come as close as arm’s length during your viewing session; however, there is absolutely no touching allowed. Manta rays are not dangerous. They are gentle giants and will maneuver around you.

GUARANTEE:  If for any reason we are unable to view manta rays on the date and time you have joined us, we will gladly offer you an opportunity go out a second time at no additional charge on a space available basis. Therefore, we recommend you plan your Manta Ray Adventures early during your visit to Hawaii.)
