Go whale-watching off the coast of Oahu on this excursion from Waikiki or Ko Olina. During the months from December to May, pods of humpback whales migrate through Hawaii's warm waters, and this tour guarantees whale sightings. With a small group of people, watch the gentle giants swim, feed, breach and play around your boat. In the rare event that you don't see any whales, you will be allowed to do the tour again for free. Snacks and round-trip transportation from Waikiki hotels are included.
