Kihei, Maui: Guaranteed Whale-Watching Tour by Raft

About This Experience

This is the short, quick winter option from South Maui. Redline Rafting runs a 90-minute whale watch from Kīhei Boat Ramp on a large, sturdy raft, with a marine naturalist on board and a hydrophone so you can listen for singing males. The listing caps each trip at 20 guests, which the operator points out is a smaller group than most whale tours. The bookable season runs from 13 December 2026 to 31 March 2027, squarely inside the January to March peak that NOAA’s Sanctuary describes.

The raft explains the strict entry rules. Redline sets a minimum age of 8 and a maximum recommended age of 65, citing the adventurous nature of its tours, and asks that nobody pregnant, nobody with a back, neck or spinal injury and nobody with poor cardiovascular health come along. The listing also calls the trip suitable for all fitness levels, but a fast raft can bounce when the wind is up, so take the back and neck warning seriously. Younger children, older travelers and anyone with a bad back will be more comfortable on a catamaran from Māʻalaea; our review of Pacific Whale Foundation’s trip is a good place to compare.

The title promises a guaranteed sighting and the inclusions repeat “Guaranteed to see Whales”, but the Viator listing does not say what you get if a trip finds none, so ask Redline before booking if that matters to you. Raft or not, federal rules keep every vessel at least 100 yards from humpbacks, and if a whale surfaces near the stopped raft the crew waits for it to move on. Reviewers from the 2026 season describe plenty of whales and the odd breach, but no trip can promise what the whales will do.

It costs from $100 per person on Viator, rated 4.9 from 696 reviews, with free cancellation up to 24 hours before. There is no hotel pickup, and parking above the ramp is free. Kīhei Boat Ramp is about 2 miles, or 6 minutes, from central Kīhei and from Wailea, so the trip suits anyone staying in South Maui who would like to skip the drive to Māʻalaea. Redline’s five-hour Molokini snorkel uses the same kind of raft but is a different day with different rules; see our review.

What's Included

• ✓ Whale watch on a large raft limited to 20 guests
• ✓ Commentary from an onboard marine naturalist
• ✓ Hydrophone to listen to whale song
• ✓ Free parking in the dirt lot above Kīhei Boat Ramp
• ✓ A sighting guarantee as worded in the listing (terms not spelled out)

Not Included

What to Bring

• A light layer, since it feels cooler on the water in the wind
• Mineral sunscreen (zinc oxide or titanium dioxide); Maui County allows only mineral sunscreens to be sold
• A dry bag or zip bag for your phone and camera, as a low raft can take spray
• Motion-sickness medicine taken well before boarding if you need it, after asking a pharmacist
• Your confirmation, so you know which check-in spot applies to your departure time

Good to Know & Caveats

• Bookable 13 Dec 2026 to 31 Mar 2027. The operator's description mentions whales from December to May, but this trip ends with March.
• Minimum age 8, and a maximum recommended age of 65 because of the adventurous ride.
• Not for pregnant travelers or anyone with back, neck or spinal injuries or poor cardiovascular health.
• The listing promises whales (“Guaranteed to see Whales”) without stating the remedy if none are seen; ask Redline what it offers before you book.
• Rafts follow the same 100-yard federal approach rule as every other boat. Whales sometimes surface near a stopped boat, but no trip can promise a close pass or a breach.
• Check in 30 minutes before departure: in the parking lot for the 7 a.m. trip, at the picnic tables above the dock for 9 and 11 a.m.
• Expect some spray on a low, open raft and keep electronics bagged.
• Free cancellation up to 24 hours before departure.
