Enjoy Hawaii's #1 marine encounter, a beautiful Kona sunset at sea, followed by a night snorkel with the majestic hahalua (manta rays). Hawaii is one of the few places in the world where couples can experience this amazing adventure. A manta guarantee promises that if couples do not see manta rays during their tour, they may re-book again (for free/subject to availability) until they get to see one. It is one of the best manta guarantees in the industry! Duration: 2.25 hours
