• 75-6082 Ali‘i Dr - Experience an extraordinary Manta Ray Night Snorkel in Kona, one of the few places worldwide where you can swim with manta rays after sunset! Following a brief 3-minute boat ride from the harbor, participants will enter the water and float on the surface, holding onto our specially designed light board. The intense 150,000+ lumen dive lights attract plankton, which in turn lure the graceful manta rays to glide and feed just inches beneath you. This awe-inspiring, close-up encounter is led by our expert team, including a licensed captain, swim guide, and certified lifeguard. Water time ranges from approximately 20 to 40 minutes, depending on various factors such as ocean conditions.

All participants must be proficient swimmers and comfortable in open ocean conditions. Wetsuits and lifejackets are available for optional rental and can be arranged during check-in at our BIO storefront. Masks and snorkels are provided, or you may bring your own. If manta rays are not spotted, Viator bookings are eligible for complimentary rebooking (subject to availability). Please be aware that delays may occur due to wildlife activity, weather, or dock traffic.
