I wholeheartedly recommend the Pacific Whale Foundation for any type of ocean wildlife watching. We took the midday whale watch cruise ( reasonably priced at about $30.00 ) and loved it so much that we went back for the Sunset Cruise ( $60.00 Included cocktails and appetizers.) Consider becoming a member and you receive a free whale watch ticket to use right then or later as a gift. Both trips had multiple sightings, many just yards from the boat. Very exciting! Spinner dolphin chased along side during the mid day cruise. I personally preferred the laid-back atmosphere of the evening trip. Hats off to the entertainment. A gorgeous sunset, mellow ukulele tunes and a little bit of humor (and two mai tais) made this the most memorable two hours of my visit to Maui.
Whale sightings are gauranteed or they will send you out again for free.
