Deep Research Report

Last updated: April 23, 2026

What it is

My Kona Adventures is a Hawaiian and disabled veteran-owned tour operator based in Kailua-Kona, on the Big Island. They specialize in small-group boat excursions, typically accommodating up to 12 passengers on a 23-foot rigid hull inflatable boat (RHIB). Their offerings include the highly popular Manta Ray Night Snorkel, day snorkel tours to locations like Pawai Bay and Captain Cook areas, and seasonal whale watching. The company emphasizes providing personalized experiences with a focus on Hawaiian history and marine life.

Visitor experience

Travelers choose My Kona Adventures for an intimate and personalized ocean adventure. The small group size (up to 12 guests) allows for more customized care and interaction with the crew. A highlight is the Manta Ray Night Snorkel, where participants can witness manta rays feeding on plankton attracted by lights, often getting very close to the animals. Day tours offer opportunities for snorkeling, viewing coral reefs and sea life, and potentially cliff jumping, with guides sharing knowledge about marine biology and local history, including the story of Captain James Cook. Crew members are present in the water with guests, particularly during snorkeling activities, enhancing both safety and engagement. The company strives to create memorable experiences, often cited by visitors as a trip highlight.

Logistics

  • Area & Access: My Kona Adventures operates from Kailua-Kona, with tours departing from either Keauhou Bay (adjacent to the Sheraton resort) or Kailua Pier.
  • Reservations: Booking tours in advance, particularly for popular experiences like the Manta Ray Night Snorkel, is recommended. Information on specific booking procedures is available on their website.
  • Timing: Guests should arrive 40 minutes prior to their scheduled boat tour departure. Tour durations vary: the Manta Ray Night Snorkel is approximately 90 minutes including check-in, the Wildlife and Reef Adventure is 1.25 hours, and other Kona tours range from two to four hours. Whale watch tours are typically 2.5 to 4 hours, depending on the season.
  • Parking: Parking can be challenging, especially in the afternoon. For Keauhou Bay departures, options include parking along the road or using the Sheraton's parking lot. The Kona trolley also services the Sheraton, offering an alternative for those without a car.
  • Permits: No specific visitor permits are mentioned as required, as this is a guided tour operator.
  • Likely Duration: Varies by tour, from 90 minutes to four hours. The Manta Ray Night Snorkel is a shorter, focused activity, while day tours offer a more extended experience.
  • Activity Type: These are half-day activities or anchor activities, depending on the specific tour chosen. The manta ray snorkel is a focused experience, while longer day tours can be a significant part of a day's itinerary.

Safety and cautions

  • Swimming Ability: Participants are required to be experienced swimmers.
  • Marine Life Interaction: Manta rays are described as harmless, lacking stingers or teeth. Guides provide information and ensure a safe viewing distance.
  • In-water Guidance: Crew members are always in the water with guests during snorkeling activities, offering guidance and assistance.
  • Night Snorkel Specifics: During the Manta Ray Night Snorkel, participants are encouraged to hold onto a provided board and are not permitted to dive down. Day trips allow for free diving.
  • Seasickness: For those prone to motion sickness, it is advised to take preventative medication an hour before the trip, or even the night before if easily affected.
  • Equipment: Snorkel gear is provided. Wetsuits are included for full-fare bookings, but may have a rental fee for discounted rates or voucher bookings.
  • Cancellations: Tours canceled by the operator due to weather conditions will receive a full refund. Guest cancellations must be made outside of a 48-hour window to be eligible for a refund.
  • Manta Ray Sightings: While sightings are common, they are not guaranteed. For full-fare guests, My Kona Adventures offers a free re-ride if no mantas are seen. Discounted or voucher guests incur a $30 re-ride fee in such cases.

Editorial take

My Kona Adventures is an excellent choice for travelers to the Big Island seeking a personal and educational marine encounter, particularly the iconic manta ray night snorkel. Its commitment to small group sizes makes it ideal for families or individuals desiring a less crowded and more attentive experience. Those who prioritize learning about local marine life and Hawaiian history from knowledgeable guides will find this operator a good fit. It's a priority activity for visitors interested in direct, guided ocean interactions.

Travelers who are not confident swimmers should skip this activity due to the explicit requirement of being an experienced swimmer. Those who prefer very large boat tours with more amenities might also find the 23-foot RHIB too rustic for their taste.

It's important not to confuse My Kona Adventures with similarly named operators such as Kona Ocean Adventures or Hawaiian Adventures Kona, which are separate companies, although they may offer comparable types of tours.
