What to Expect

1. You receive an assigned check-in time at Keauhou Bay that the operator may move for weather, sunset timing or boat capacity, so keep your phone on.
2. After a briefing you board for a 3-minute ride to the manta site off Keauhou, where other operators' boats also gather.
3. Guides position you along a custom light board; you float face-down with mask and snorkel while mantas feed on plankton drawn by the lights, about 30 minutes in the water.
4. You return to the harbor about 80 minutes after departure; wetsuits and underwater cameras are available to rent, and the operator suggests a towel and warm layer.
