Thousands of humpback whales migrate to Hawaii's warm ocean waters each winter. The majority of the whales are found off the coast of Maui. You can see whales from late November through mid-May, but the peak of the season is in February and March. The Pacific Whale Foundation offers 16 whalewatch cruises each day during the winter season, each one staffed by a team of certified marine naturalists. You are guaranteed to see whales or you go again free. All the profits go towards Pacific Whale Foundation's ocean research, education and conservation programs.
