Welcome to Big Island Watersports

Every watersports tour on this page leaves from Kona on the Big Island’s west coast, and each one is built around the night manta ray snorkel, Kona’s best-known ocean experience. Large manta rays feed on plankton drawn to the boat’s lights after dark, and you float on the surface holding a light board while they pass beneath you.

  • Manta Magic Night Snorkel — from $139, about 50 minutes in the water. The straightforward option if the mantas are all you want.
  • Sunset & Manta Ray Snorkel Combo — from $135, about 2 hours 15 minutes. Adds a sunset cruise before the manta dive, for little or no extra cost.
  • Whale Watch & Manta Snorkel Combo — from $219, about 3 hours. A winter-only trip that pairs humpback whale watching with the manta snorkel, departing from the Kealakehe Parkway area near Honokōhau Harbor.

  • Hawaii's manta rays are called hahalua. At night they feed on plankton drawn to underwater lights, which is why every manta trip here runs after dark.
  • On the Manta Magic snorkel you float on an illuminated light board for up to 40 minutes while manta rays with wingspans of up to 16 feet feed below.
  • The Manta Magic operator is Green Listed by Manta Ray Advocates of Hawaii, and certified marine biologists are on board.
  • From December through April, the whale watch combo adds an hour with humpback whales, with a hydrophone so you can hear them sing.
  • Non-snorkelers can book a ride-along place on the sunset and manta combo and watch from the boat.
