Big Island Whale Watching: A Small Raft Into the Humpback Nursery off Kawaihae

Every winter thousands of humpback whales swim down from Alaska to give birth and mate in warm Hawaiian water, and the calm Kohala Coast is one of their favorite nurseries. Big Island whale watching from Kawaihae puts you right in it within minutes of leaving the harbor. This trip runs two hours on a small raft-style boat that sits low to the water, with a hydrophone to hear the whales sing.

This page covers when to go, what the trip is like, what it costs, and how to get the best odds of a breach.

Why this made our list

The harbor is the first reason. Kawaihae sits at the north end of the Kohala resort coast, minutes from Waikoloa, Mauna Lani and Mauna Kea, and the boat is in the humpback nursery grounds within minutes of leaving the dock. You spend your two hours with whales rather than motoring to find them.

The boat is the second. It is a high-performance raft, similar to a Zodiac, that holds at most 20 guests. Sitting close to the water puts the whales at eye level, keeps motion low, and lets the captain reposition quickly when a whale surfaces somewhere else. When things go quiet, the crew drops a hydrophone over the side, and you hear the males singing under the boat.

The third is the crew. The captains know whale behavior well, and they explain what you are seeing as it happens: a mother resting with her calf, a curious calf inspecting the boat, or a competition pod of males charging after a female. That is why the trip holds a 4.9 rating across 634 reviews.

Why this operator

Whale watching runs out of Kona, Kawaihae and Hilo, on everything from big catamarans to small rafts. The big catamarans from Kona and Waikoloa are comfortable, often have a bar, and suit anyone who wants shade and a restroom. The raft is for people who want to be close to the water and close to the whales. Out of Kawaihae, it is the trip we book. If you would rather pair whales with snorkeling on the Kona side, the Kealakekua Bay Zodiac tour sees whales in season too.

What Big Island whale watching is like

The trip runs about two hours dock to dock. Here is how it goes.

1. Check in at the Kawaihae South Boat Ramp. Arrive 30 minutes early. It is a barefoot boat, so your shoes are collected before you board.
2. Into the nursery. The raft leaves the harbor and enters the nursery grounds quickly, where mothers and calves rest and play in the shallower water.
3. Find the action. The captain watches for blows, tail slaps and breaches and moves the boat to where the whales are most active, always at a respectful distance.
4. Listen. The hydrophone goes over the side and you hear the humpback song live.
5. Watch behavior. With luck you see a competition pod, a breach, or a calf curious enough to check out the boat. The crew explains it all as you go.
6. Run home. Snacks and drinks come out on the ride back to the harbor.

Prices and what you get

The whale watch is from $95 per person plus tax and booking fees; adult and child rates are on the booking page. That covers two hours on the water, the hydrophone, a narrated trip from captains who know whale behavior, snacks and drinks, and dry storage for your gear. A tip for the crew is customary.

Trips need at least six guests to run. If the minimum is not met, the operator contacts you the day before to discuss options.

Who it’s for (and who should skip it)

Anyone visiting between December and April who wants to see humpbacks up close: families with kids 3 and older, couples, photographers and anyone staying on the Kohala Coast. It is a short trip, so it fits easily into a beach day.

Skip it if you are more than six months pregnant or have a neck or back injury; a raft moves in a way a big catamaran does not. Skip it if you want shade, a restroom and a cocktail; a larger boat suits you better. Outside whale season, put the time toward the Kona sunset sail instead.

Where to check in and how to get there

The boat leaves from the Kawaihae South Boat Ramp, also called the Kawaihae Small Boat Harbor south basin. From Waikoloa or Mauna Lani, drive about 12 miles north on Highway 19, turn left onto Kawaihae Road, and take the first harbor entrance; your confirmation has the gate-by-gate directions to the ramp and the bathroom building. Look for the yellow boat at the dock. From Kailua-Kona, allow about 45 minutes to an hour.

Park in the marked stalls or gravel areas, away from the trucks with trailers.

Best time to go

Time of year. Humpbacks are in Hawaiʻi from about December through April, with the peak from January through March. This operator runs from mid-November through April and advertises guaranteed sightings from January 1 to March 15. Our best time to visit the Big Island guide covers how whale season fits with the rest of the year.

Time of day. The Kohala Coast is usually calmest early, before the afternoon wind picks up, so take the earliest departure on your date. That said, the crew notes that some of the best whale activity happens in less than perfect weather, and the trip runs rain or shine.

Local tips before you book

• Book January to mid-March. That is the peak of the season and the guaranteed-sighting window.
• Wear slip-on sandals. Shoes come off at the dock.
• Bring a windbreaker. It is an open boat, and the spray is part of the deal.
• Take seasickness medicine early. The crew recommends the night before and the morning of, not right before boarding.
• Use mineral sunscreen. Hawaiʻi law bans oxybenzone and similar chemicals that harm reefs.
• Pair it with the beach. A morning whale watch leaves the afternoon for the Kohala Coast beaches; see our things to do on the Big Island guide for ideas.

The verdict

If you are on the Big Island between January and March, go whale watching, and if you are staying on the Kohala Coast, do it from Kawaihae on this raft. Minutes to the nursery, low to the water, a hydrophone to hear them sing, and a crew that knows what the whales are doing. Wear sandals, bring a jacket, and book early in your trip in case the weather moves you to another day.
