Board a small 12-passenger boat at Keauhou Harbor for an intimate night snorkel beneath lights as manta rays feed on plankton. This short ride and 30–45 minute water session focuses on respectful, close-up viewing of Kona’s famous mantas.

The harbor lights thin as the boat slips beyond Keauhou’s breakwater and the Pacific opens into ink-black water punctuated by the glow of a single lightboard. You feel the ocean breathe under the hull; the captain eases the throttle and the guide briefs the group in low tones. In minutes you’re at "Manta Village," where lamps pull plankton to the surface and the water below becomes a stage.

History
Kona’s manta night snorkels began as local research and community-led viewing efforts; operators now follow strict lighting and distance guidelines developed with scientists and managers.
Conservation
Responsible operators are often Green Listed and limit group size and light use; choose companies that follow no-touch, no-chase rules and use reef-safe products.

Book early in your trip
Manta sightings are common but not guaranteed; reserve a slot early in your stay to allow for a free rebooking if manta activity is low.
Arrive 30 minutes early
Check-in and wetsuit fittings happen before boarding; arriving early reduces stress in the dark harbor.
Use reef-safe sunscreen
Apply reef-safe sunscreen before the tour and avoid lotions just before entering the water to protect marine life.
Bring a warm layer for the return
Even in Hawaii the night ride can be cool—pack a light jacket or cover-up to stay comfortable after snorkeling.
Mask and snorkel
A properly fitting mask makes the viewing more comfortable and lets you focus on the mantas rather than adjusting gear.
Wetsuit (shorty or full)
Optional for warmth and buoyancy—operators provide or fit suits if you prefer.
Reef-safe sunscreen
Protects your skin and reduces chemical runoff that can harm marine ecosystems.
