Kailua-Kona: Night Manta Snorkel or Dive

If you’re heading to Hawaii’s Big Island, a night with the manta rays in Kailua-Kona is often touted as a must-do experience. This tour promises a chance to see these majestic creatures glide effortlessly through the water in their natural environment. We haven’t personally been on this tour, but based on the available information, it’s clear that many travelers find it a highlight of their trip.

What we like most about this experience is its accessibility—whether you prefer snorkeling or diving, the setup caters to different comfort levels, and both options bring you close to the action. The calm, protected waters of the bay provide a safe, unobstructed view of the manta rays’ awe-inspiring flips and glides. The other aspect that excites us is the chance to witness these gentle giants feeding on plankton, illuminated by plankton-attracting lights—a surreal sight that captures the magic of Hawaii’s night ocean life.

On the flip side, a consideration for potential participants is the activity’s dependence on weather and marine conditions. If the weather doesn’t cooperate or if the tour is canceled at short notice—as some reviews report—you might not get your chance to see the mantas. Also, this experience isn’t suitable for everyone: non-swimmers, those with back problems, and anyone prone to seasickness might find it less enjoyable or challenging.

This tour suits travelers who love marine life, seek unique experiences beyond the typical beach day, and are comfortable in the water. It’s perfect for those who value authenticity and are eager to see the ocean’s gentle giants perform their nightly routines.

What Makes This Tour Stand Out?

The main draw of this tour is the chance to observe Kona’s famous manta rays in their natural setting. These creatures are among the most gentle and fascinating marine animals, and their nighttime feeding habits provide a spectacle that many say ranks among the top ten dives worldwide. The experience takes place in a serene, sheltered bay with calm waters, usually suitable for both snorkelers and divers, making it a flexible activity for various skill levels.

The lighting setup is a key part of the experience. The boats anchor over a sandy area descending to about 30 feet deep, where special lights attract plankton, the manta rays’ main food source. The mantas, wingspans reaching 15 feet, glide through this illuminated zone, often performing continuous flips as they seize mouthfuls of plankton. Seeing these gentle giants perform underwater aerobatics is as close to a living ballet as you’ll get.

The Itinerary and What to Expect

Most tours are around two hours long, usually scheduled in the evening when manta rays become active. The experience begins with the boat ride out to the designated feeding zone, which is often a short trip from the harbor. Once anchored, participants gather around the boat’s lights, or in the case of snorkelers, float above the action with masks and snorkels provided. Divers have the option to gear up and descend, reaching the same feeding zone.

You’ll find the bay’s waters are calm and clear, making it easier to spot mantas even from above the waterline. The lights’ glow creates a magical atmosphere, with plankton clustering around the light, and the mantas swirling through the illuminated water. As one review notes, “The remarkable aspect of this adventure is the concentration of plankton attracted by the lights,” which means you’re viewing the mantas in a natural yet enhanced environment.

The Practical Details

Included in the tour are snorkeling gear, which makes it easier to relax and focus on the spectacle. Light snacks and some non-alcoholic drinks are also provided, adding to the comfort. You’ll want to bring swimwear, a change of clothes, a towel, snacks, water, and a waterproof camera to capture the magic. Make sure to apply biodegradable sunscreen to protect the marine environment.

The tour does not include towels or transportation, which you might need to organize separately. If you choose the diving option, gear rental on-site costs $40—a reasonable fee given the quality of the experience.
