The whale-watching cruises, which depart several times a day in winter, are immensely popular. In the unlikely event you don’t spot whales, your next trip is free. Well-versed naturalists add context to the trips. Snorkel and dolphin-watching cruises (adult/child $94/52) are popular year-round. There are other snorkeling trips as well as various sunset and dinner cruises. Most trips leave from Lahaina Harbor. Other trips depart from Maʻalaea Harbor to the south.

The company also offers several highly recommended volunteer opportunities in Maui through its Volunteers on Vacation program.
