Pacific Whale Foundation is a research and conservation charity that happens to run one of the biggest whale fleets in Hawaii. It was founded on Maui in 1980 by Greg Kaufman to study a declining humpback population, and its scientists began offering weekend whale watches to fund the weekday research. That arrangement is still the whole point: PacWhale Eco-Adventures is wholly owned by the foundation, and its profits go back into the science.
A classic two-hour whale watch costs $99.05. A small-group version on a smaller boat is $129.95.
What it actually is
A 501(c)(3) non-profit with a commercial arm, rather than a tour company with a charitable veneer. The structure is stated openly: the foundation owns PacWhale Eco-Adventures, the Māʻalaea Ocean Store and the online store, and its financials are published in annual 990 filings.
The research shows up in the product. Guides are Certified Marine Naturalists rather than generic crew; vessels operate to safety protocols the foundation says it developed with government bodies and other organizations, including one called Go Slow – Whales Below; and the company's work on humpbacks, spinner dolphins and the endangered false killer whale is the material the commentary draws on. It runs a live whale and dolphin sightings map and community-science programs including a shore-based Great Whale Count.
Boats, harbor and season
Five vessels, four with an inside cabin. Ocean Guardian and Ocean Voyager are the large catamarans and the two with ramp access; Ocean Discovery handles dinner cruises; Ocean Spirit is a sailboat; Ocean Explorer is the smallest, with no inside cabin and a minimum age of 7 on the small-group whale watch.
All of it departs Māʻalaea Harbor. The foundation says it currently operates only from there, having lost its Lahaina Harbor base to the wildfires, and that it is deliberately pausing on any return while the community recovers. Check-in is at the Ocean Store in the Harbor Shops, 45 minutes before departure, and the walk to your dock can be a quarter of a mile.
The whale season runs November to May, peaking mid-January to March, which matches NOAA's sanctuary window. The company claims more daily whale departures than any other Maui operator, from sunrise to sunset.

Sighting guarantee
Sightings guaranteed or go again free on another whale watch of equal or lesser value, within one year.
- Wording
- "Whale sightings are guaranteed or go again free on another whalewatch of equal or lesser value within one year"
- Claimed rate
- "We are proud of our 97% sighting success rate"
- Expiry
- One year from the date of the trip

- Accepted up to 48 hours before the scheduled date; the terms state that bookings are otherwise final
A re-ride, not a refund. Equal or lesser value means a $189.95 dinner cruise does not entitle you to a second dinner cruise if the whales are elsewhere.
What you are actually buying
Two things separate this from a standard catamaran trip, and both are checkable.
The first is where the money goes. PacWhale Eco-Adventures is not a company that donates to a charity; it is owned outright by one, and its terms name Pacific Whale Foundation as a 501(c)(3) with a federal tax ID. Retail and tour proceeds fund the research, education and conservation programs — marine debris monitoring, reef cleanups, the Great Whale Count, drone studies of false killer whale body condition.
The second is the commentary. Guides are Certified Marine Naturalists working from the foundation's own datasets, which is why the identification talk on a PacWhale boat runs deeper than a scripted tour. The foundation's research has fed protections for humpbacks, spinner dolphins and the endangered false killer whale.
There is a sustainability claim attached too: the company says the majority of its catamarans run on biodiesel, that food waste is composted, and that onboard cutlery, cups and plates are reusable metal and dishware. Those are the operator's own statements rather than a certified standard, so weigh them accordingly.
Before you book
Parking at Māʻalaea is paid and run by third parties with no validation, so arrive early and budget for it. Check-in is 45 minutes ahead and the crew gathers everyone 20 minutes before departure. Neither the store nor the boats take cash.
Hawaii permits only mineral sunscreen with zinc oxide or titanium dioxide as the active ingredient, and no aerosols. All vessels have at least one restroom. Dietary requirements on the food cruises should be flagged when booking.
How it compares
Ultimate Whale Watch & Snorkel is the other name worth knowing on Maui, and it is the mirror image: rafts seating 18, low to the water, out of Mala Boat Ramp, from $77, with strict boarding rules and no restroom on most boats. Pacific Whale Foundation is the choice for shade, stability, children, accessibility and the science; Ultimate is the choice for proximity and a small group. Neither can legally get you closer than 100 yards to a humpback.
Our call
The Maui trip where the ticket does something after you get off
PacWhale Eco-Adventures is wholly owned by a 501(c)(3) that has been studying humpbacks since 1980, its naturalists are certified, it runs more departures a day than any Maui operator, and its safety protocols come out of its own research.
Skip it if If you want a small boat close to the water — the rafts out of Mala Boat Ramp are a different experience entirely.
Compare Maui whale tripsQuestions people ask
Is Pacific Whale Foundation really a non-profit?
Yes. It states that it is a 501(c)(3) non-profit organization with federal tax ID 99-0207417, founded in 1980 by Greg Kaufman. Its tour operation, PacWhale Eco-Adventures, is a wholly owned social enterprise whose profits fund the foundation's research, education and conservation work.
When is the Maui whale season?
The company puts whale watching season at November to May with a peak between mid-January and March, and says its season opens in early November with a Welcome Home the Whales cruise — while noting occasional first sightings as early as late September or October.
Where do the boats leave from?
Māʻalaea Harbor. Check in at the foundation's Ocean Store in the Harbor Shops at 300 Maʻalaea Road, next to Maui Ocean Center, 45 minutes before departure. The company says it is currently operating only from Māʻalaea, having lost its Lahaina Harbor base in the wildfires.
How much is a whale watch?
$99.05 for the classic two-hour cruise and $129.95 for the small-group version. Whale watch sails run $119.95 to $159.95, a sunset cocktail whale sail $149.95, and the sunset dinner and whale watch $189.95.
What whales will I see?
Humpbacks, overwhelmingly. The company also lists melon-headed, short-finned pilot, pygmy and endangered false killer whales in Maui waters, and says the main Hawaiian Islands insular false killer whale population numbers fewer than 200 animals.
Is it accessible?
Partly, and it depends on the boat. Ocean Guardian is the only vessel with a wheelchair-accessible restroom; it and Ocean Voyager share an accessible boarding ramp. Wheelchairs must be lightweight and foldable, electric chairs are not permitted, and crew cannot lift guests, so you need a companion who can assist.
How close do the boats go?
No closer than federal law allows. In Hawaii it is prohibited to approach a humpback within 100 yards on or in the water and within 1,000 feet by air, year-round. The company says its vessels operate to marine animal safety standards drawn from its own research, including a Go Slow – Whales Below protocol.
