Maui activities range from snorkeling and diving, to cycling and tours. Although staying in one of these vacation rentals and getting pampered is a plus, exploring the various activities of Maui is a must. You can experience one of the more unusual opportunities to take a van to the top of Haleakaka and then ride a bicycle 39 miles down to Paia without pedaling once. Also, Maui's best-known snorkeling and diving spot is the tiny crescent of Molokini, where you can see many species of fish, including deep-water ones.
