From late December through early May, thousands of humpback whales migrate to the warm waters of Hawaii. Catch a glimpse of the magnificent mammals on a whale-watching excursion from Waikiki. Venture out on the water with a small group of people to witness the humpback whales breach, play or feed around you. Your guide guarantees sightings, and in the rare event that you don’t see any supersize stars, you get to do the tour again for free!
