Wailuku is located just west of Kahului, at the mouth of the Iao Valley. In the early 20th century Wailuku was the main tourist destination on Maui, though it has since been eclipsed with the rise of the resort towns such as Ka'anapali, so much that there are no hotels to speak of in Wailuku. It is, however, a pleasant community that tourists may wish to visit on a day trip.
There are two ancient temples near Wailuku, called heiaus - the Haleki'i Heiau and the Pihanakalani Heiau. Both date back hundreds of years, and were used for human sacrifices by the native Hawaiians.
Wailuku is located at 20°53'31" North, 156°30'8" West (20.891923, -156.502177)1.
