Just off the coast of Kailua-Kona, Hawaii, the waters of Keauhou Harbor offer one of the most spellbinding marine encounters on the planet: snorkeling alongside graceful manta rays. Ninth Island Nation’s shared charter invites adventurers to step aboard a boat for a brief but unforgettable one-hour journey into the ocean’s twilight, where underwater lights attract plankton—nature’s irresistible bait for these giant, gentle creatures.

This particular snorkeling spot holds a special place in local history. Nearly fifty years ago, the nearby Outrigger Hotel pioneered the practice of illuminating the waters, drawing mantas close to feast and captivating early visitors. Today, Ninth Island Nation continues this tradition by mimicking that luminous invitation, creating a safe, controlled environment for swimmers to witness mantas’ striking wing-like fins sweeping through illuminated plankton clouds.

What makes this experience stand apart is its intimacy and accessibility. Unlike distant boat tours or large, crowded operations, this shared charter maintains small groups, allowing for close encounters without overwhelming the wildlife. Keauhou’s volcanic coastline offers a striking backdrop of rugged lava rock that contrasts vividly with the soft gliding motions of the mantas below. The water is typically calm and clear, enhancing visibility and comfort.

Ninth Island Nation anchors itself firmly in Hawaii’s vibrant outdoor recreation scene. The company’s focus on sustainable encounters respects the delicate ocean ecosystem while delivering encounters that blend thrill and education. This is not only a spectacle for seasoned snorkelers but also a welcoming introduction for families and first-timers looking to connect with Hawaii’s marine treasures.

For travelers based in Kailua-Kona, this activity is a must-do highlight that captures the spirit of Hawaii’s wild ocean in a brief but powerful marine adventure.
