"A 5.5-miler on a secluded stretch of South Maui, Hoapili Trail was once a highway reserved for Hawaiian royalty. Today it traverses a part of the island that most visitors never see. Budget more time than you typically would for a hike of this length, as there are some really exceptional viewpoints over La Perouse Bay. Off the main trail, a number of spur trails lead to places like Keawanaku Beach—which is often totally empty—as well as the Cape Hanamanioa lighthouse and ruins from ancient fishing villages." - Todd Plummer
