Snorkel Big Island is a Kailua-Kona, Hawaii–based snorkeling operator specializing in manta ray night snorkels and daytime reef trips. The company runs small, personalized groups led by experienced crew and licensed captains, offering safe, guided excursions from Honokohau Harbor and nearby launch points along the Kona Coast.
For more than 12 years Snorkel Big Island has operated manta ray snorkel excursions, focusing on attention to detail, safety, and expert guides. Trips include Honokohau Manta Ray Night Snorkel, a dedicated night snorkel to manta aggregation sites; morning and morning 2.5-hour snorkels along the Kona Coast; and 4-hour Kealakekua snorkel trips that may visit the Captain Cook Monument or secluded reefs depending on conditions. All listed tours provide snorkel gear and, on longer trips, snacks as indicated.
Safety requirements are clearly communicated: prior swimming and snorkeling experience is required for manta tours, guests must be able to independently climb a side or vertical boat ladder, and some trips are not recommended for pregnant guests or those with recent surgery or mobility restrictions. Check-in times may be up to forty minutes before departure.
As a family-run business, Snorkel Big Island emphasizes stewardship of land, ocean, and wildlife, and prides itself on personalized service and expert local knowledge. Guests are encouraged to arrive on time for their scheduled tour to ensure the best possible experience. Licensed captains and dedicated guides select manta sites near the Kona airport or Keauhou based on sightings to maximize chances of close encounters with giant manta rays for visitors.
