Waikiki and the North Shore get most of the attention on the island of Oahu, and for good reason. Oahu is the surfing capital of the world and has something to offer every skill level, but hiking on the island of Oahu is one of its best-kept secrets!
One of my favorite hikes is the Lanipo Trail. It is a a strenuous 7.5 mile (12 km) hike that can take 4 to 6 hours depending on conditions (I would not recommend doing this hike when it's wet), but the scenery and experience offered by this hike is definitely worth the effort!
The hike along the Mauna Lani Heights ridge, above the neighborhood of Kaimuki, offers breathtaking views of the island and Honolulu. The terrain is diverse, and at times you are hiking on steep boulders, and others navigating thick jungle. There is one section of the trail that carves through tall bamboo that clank together when the wind blows—like a natural wind chime. You will not be disappointed with the summit and the sense of accomplishment that you feel when you get there!
