A two-hour boat ride takes visitors to see Hawaii's most impressive residents - its whales. On most trips, boats are able to get so close that observers can see the barnacles on the whales' backs, and may get sprayed by the splash as their great tales slap the water's surface. You can also expect to hear the whales as they converse with each other in their clicking, singing "language."

Whalers Village Museum
Kaanapali Beach, Lahaina
This museum, in the heart of Lahaina, documents the sleepy port city's evolution to a whaling boomtown. Home to an impressive collection of whaling memorabilia, the museum shows what life was like between 1825 and 1860 for the men who led the harsh whaling life aboard tiny boats chasing 45-ton quarry. The exhibit includes harpoons, sea chests and a re-creation of the typical six-man crew's quarters. Films about whales and whaling history are shown throughout the day.

Since more than half of the island is inaccessible by car, visitors may choose to take this memorable flight over Haleakala's crater and the surrounding volcanic landscape. Children should be equally thrilled at the experience of riding in a helicopter and the magnificence of the view.
