About This Experience

Calypso is the big-boat, family-friendly way to Molokini. The catamaran has three decks, two water slides, a jumping platform and a glass-bottom viewing room, so anyone who would sooner stay dry still has plenty to do. The day runs about five and a half hours from Māʻalaea Harbor, with breakfast, lunch with chips, potato salad, fruit and veggie platters and cookies, and coffee, tea, sodas and juice. Snorkel gear and flotation devices are included.

Molokini lies about 3 miles offshore. It is the southern rim of an extinct volcanic crater, and its cove is a state Marine Life Conservation District where you look and do not touch, feed or collect. The second stop is the reef area operators call Turtle Town off Mākena; give green sea turtles at least 10 feet, as NOAA asks in Hawaiʻi. The captain chooses the snorkel sites each morning according to weather and swell, so Molokini is never certain, and the listing says wildlife is likely but not guaranteed.

Calypso prices its extras up front, so budget for them. Alcohol is $3 a drink and is served only after the snorkeling ends (21 and over, with photo ID). Wetsuits rent for $10, Dramamine is $5 for two tablets, T-shirts are $20, and an onboard underwater photographer sells photo packages. Towels and harbor parking are not included; Māʻalaea parking is paid by meter or QR code, and a recent reviewer warns that it is limited, so arrive early. Seating is first come, first served.

The boat is listed as wheelchair accessible for manual chairs up to 28 inches wide; motorized chairs and scooters cannot be carried. Children must be with an adult, basic swimming ability is recommended, and the listing advises against the trip for anyone with poor cardiovascular health. Calypso runs in most weather, so dress for wind and spray.

It costs from $189 per person on Viator, rated 4.6 from 2,230 reviews, with free cancellation up to 24 hours before. GetYourGuide sells the same Calypso trip as South Maui: Molokini Snorkeling Adventure for $190 (4.6 from 482 reviews), with free cancellation up to 2 days before.
