There are many historical landmarks on Maui, and the entire Hawaiian Islands in general. Many don't know that Maui's whaling town of Lahaina used to be the capital of the Hawaiian Islands over 75 years ago. In Lahaina there are various landmarks to visit such as the whaler's museum, the biggest banyan tree in the world, and the oldest school west of the Mississippi River (Lahainaluna).
There are a couple landmarks in Hana that are popular on most tourist lists. The Seven Sacred Pools provide an unbelievable setting of tranquility. Just a short drive from the pools is Wai'anapnapa State Park, where you can walk on a black sand beach or swim in underwater caves.
