Oahu tours & activities, fun things to do in Oahu. | HawaiiActivities.com

Nature-lovers who find themselves on Oahu from December to April won't want to miss the annual migration of humpback whales. This miraculous display occurs every winter, when the whales embark on a long journey from Alaska to raise their young in the warmer waters around Hawaii. With departure points from Waikiki, Haleiwa and Ko Olina, you can capture the majestic moment when these massive creatures breach the water from the deck of a sailing catamaran or luxury liner.
