Things to Do on Oahu: Outdoor Adventures

Don't forget to pack the sunscreen, because Oahu's endless summers mean outdoor activities abound all year long. From mountain vistas to tropical gardens and clear oceans, the Aloha State's third-largest island has something for adventure junkies and nature lovers.

Forty-four miles long and 30 miles wide, Oahu is sandwiched between parallel extinct volcanic cones—the Koolau range to the east and Waianae to the west—creating beautiful peaks, valleys and bays along 112 miles of sandy coastlines. A perfect backdrop for adventuring, Oahu's great outdoors offer underwater exploring, surfing, scenic hikes and breathtaking views. 

A few of our favorites include hiking up Diamond Head and taking in stunning coastal and city views, submerging underwater and swimming with tropical fish, kayaking to Mokulua Islands, touring the lush valleys at Kualoa Ranch or the verdant rainforest at Foster Botanical Garden—or even facing our biggest fears and skydiving over Haleiwa or cage diving with sharks. Whether it's land or sea (or both!) for your chosen Oahu adventure, you'll want to be sure to bring your camera!
