What it is

Hawaii Snorkel Tours, operating under the name Kona Manta Ray Snorkel Tours, specializes in nighttime boat tours designed for visitors to snorkel with manta rays off the Kona coast of the Big Island. This experience involves attracting plankton with powerful underwater lights, which in turn draws manta rays to feed, allowing snorkelers to observe these gentle giants up close from the water's surface. The company emphasizes safe, respectful, and educational encounters with marine life.

Visitor experience

Travelers board a boat, typically in the early evening around sunset, and are provided with snorkeling gear including wetsuits, masks, snorkels, and fins. After a safety briefing, the boat travels to a designated manta ray viewing site, often in areas like Garden Eel Cove or Keauhou Bay. Once at the site, powerful lights are deployed into the water, attracting microscopic plankton. Snorkelers enter the water and hold onto a flotation device with lights, floating peacefully on the surface. Manta rays, some with wingspans exceeding 10-15 feet, then glide, somersault, and feed just inches below the surface, creating a "surreal" and "unforgettable" underwater ballet. The experience is described as peaceful and thrilling, allowing for close observation of the mantas' graceful movements.

Logistics

  • Area & Access: Hawaii Snorkel Tours is based in Kailua-Kona. While the physical address provided is an office at 75-5919 Ali‘i Dr # M2, tours typically depart from local marinas. The website for Kona Manta Ray Snorkel Tours indicates departures from Honokohau Marina or Keauhou Bay, common points for these excursions.
  • Reservations: Booking in advance is highly recommended due to limited tour capacities, especially during peak seasons.
  • Timing: Tours are conducted at night when manta rays are most active in feeding under lights. Operators often offer sunset departures or later evening options.
  • Parking: Parking is generally available and easy at major departure marinas like Honokohau.
  • Permits: No individual visitor permits are required; these are handled by the licensed tour operator.
  • Likely duration: The actual in-water snorkeling time with manta rays typically ranges from 45 to 90 minutes. The overall tour duration, including boat travel and briefings, will be longer, often around 1.5 to 2.5 hours.
  • Pacing: This is a half-day to anchor activity, providing a distinct and memorable evening experience.

Safety and cautions

  • Manta Rays: Manta rays are gentle filter feeders and are not dangerous to humans; they lack teeth, stingers, or barbs.
  • Swimming Ability: Participants are generally required to have basic swimming skills and be comfortable swimming at least 50 yards unassisted. Non-swimmers or those uncomfortable in open water at night may find it challenging.
  • Health Restrictions: The tour may not be recommended for individuals who have recently undergone surgery, or those with significant mobility or physical restrictions.
  • Ocean Conditions: While manta rays are present year-round, ocean conditions are generally calmer and more predictable from April to October. Winter months (November-March) can bring larger swells and choppier water, which may lead to tour cancellations for safety reasons.
  • Wildlife Etiquette: It is crucial to follow guide instructions, maintain a respectful distance (typically 10 feet), and avoid touching, chasing, or cornering the manta rays. Keeping fins up prevents accidental contact with the mantas.
  • Gear: Wetsuits are provided to help with warmth and buoyancy in the nighttime water, which typically ranges from 75-82°F (24-28°C). A light jacket for the boat ride is advisable as it can get chilly.

Editorial take

This manta ray night snorkel tour is a top-tier, bucket-list experience for visitors to the Big Island, consistently rated as one of the best marine encounters in the world.

  • Prioritize it if: You are comfortable in the ocean, can swim, and are seeking a unique, mesmerizing wildlife interaction that is both thrilling and peaceful. It's ideal for couples, families (with children typically aged 5+ who can swim), and solo adventurers looking for an unforgettable natural spectacle.
  • Skip it if: You are a non-swimmer, have significant claustrophobia or fear of deep/dark water, or are prone to severe seasickness, especially if visiting during winter months when ocean conditions might be rougher. Those with recent surgeries or significant mobility issues should also reconsider.
  • Do not confuse it with: Daytime snorkeling tours, which offer reef exploration but do not typically feature the unique nighttime manta ray feeding spectacle. Also, differentiate between snorkel tours (floating on the surface) and manta ray dive tours (for certified scuba divers). While many operators offer similar manta ray night snorkel experiences in Kona, "Hawaii Snorkel Tours" (Kona Manta Ray Snorkel Tours) is one specific operator. Other reputable operators also offer this experience, such as Kona Snorkel Trips or Sea Paradise Hawaii.
