Molokini Crater + South Maui Coast Adventure from Kihei, Maui

5.0 (1,649 verified reviews)

About This Experience

This is Redline Rafting’s snorkel day, and it shares only the raft and the ramp with the company’s winter whale watch. It runs all year, leaves Kīhei Boat Ramp at 7 a.m. and lasts about five hours, with snorkel stops at Molokini and along the South Maui coast, including the reef area operators call Turtle Town off Mākena. Hot cinnamon rolls and fruit for breakfast, a deli lunch, sodas, bottled water and snorkel gear are included, and a local guide gives instruction.

Molokini sits about 3 miles off Maui’s southwest coast. It is the southern rim of an extinct volcanic crater, and the shallow cove inside is a state Marine Life Conservation District: no feeding fish, no taking coral or rock, and no landing on the islet. Recent reviewers describe three or four stops in a morning, so the crew picks the spots on the day, and as on every Molokini trip, conditions decide where you snorkel. An early start helps, since the water is usually calmer before the afternoon wind builds.

The entry rules are strict. Guests must be 8 to 65 (contact Redline for exceptions), have at least moderate fitness and be able to climb a vertical ladder to get back on the raft after each swim. The listing rules out pregnant travelers, anyone with a spinal injury or poor cardiovascular health, and elderly or fragile guests, and it advises against the trip for people who get seasick. If that leaves out someone in your group, Calypso’s triple-deck catamaran from Māʻalaea has stairs into the water, slides and a wheelchair-accessible deck; see our review.

The operator’s copy talks about swimming with green sea turtles. In Hawaiʻi, NOAA asks snorkelers to stay at least 10 feet from honu and never touch, chase or feed them, so expect to watch them from that distance. Underwater visibility claims are the operator’s own and change with the day.

The trip costs from $232 per person on Viator, rated 5.0 from 1,649 reviews, with free cancellation up to 24 hours before. There is no hotel pickup; the ramp is about 6 minutes from central Kīhei and from Wailea. For whales on the same kind of raft in winter, see our review of Redline’s 90-minute whale watch, which has its own season and rules.

Frequently Asked Questions

Where does the Redline Molokini trip leave from?

From Kīhei Boat Ramp in south Kīhei. Park free in one of the two lots above the boat-trailer lot and look for the big red boat. The ramp is about 6 minutes from central Kīhei and from Wailea; there is no hotel pickup.

How long is the trip and what time does it start?

About five hours. Check-in is at 6:30 a.m. and the raft leaves at 7 a.m., so you are back around midday with the afternoon free. Early starts are normal for Molokini trips because the water is usually calmer before the wind builds.

What is included on the Redline Molokini trip?

Breakfast of hot cinnamon rolls and fruit, a deli lunch, sodas and bottled water, snorkel gear and a guide who gives instruction. Gratuities and hotel pickup are not included. Recent reviewers mention sandwiches, homemade cookies and chips for lunch.

Who can join, and how fit do you need to be?

Guests must be 8 to 65 (ask Redline about exceptions), have at least moderate fitness and be able to climb a vertical ladder back onto the raft. It is not recommended if you are pregnant, elderly or fragile, have a spinal injury or poor heart health, or get seasick.

Will we definitely snorkel at Molokini?

Not definitely. The crew chooses the stops on the day, and Molokini depends on wind and swell, as on every trip there. Recent reviewers describe three or four snorkel stops, usually including Molokini and the Turtle Town area off Mākena.

How is this different from Redline's whale watch?

The whale watch is a 90-minute winter-only trip (13 December to 31 March) from $100, with a naturalist and hydrophone and no swimming. This is a five-hour, year-round snorkel day from $232 with two meals, gear and a ladder climb after each swim. Both leave from Kīhei Boat Ramp and share the 8 to 65 age range.

What do reviewers say about Redline's Molokini trip?

It is rated 5.0 from 1,649 Viator reviews. Reviewers from 2026 name captains and crew, describe working masks with no fog or leaks, plenty of fish and turtles, and say the breakfast and lunch were the right amount. One nervous first-timer says the crew put them at ease.
