Tropical breezes, lush foliage, volcano-studded landscapes—Oahu has all the scenery Hawaii’s known for, and a pretty incredible historical side, too. You'll find the Pearl Harbor memorial here, as well as Iolani Palace, the former royal residence. Oahu's surfing legacy goes back before the 1800s—and ask anyone who knows their way around a longboard, the waves are some of the best in the world. Travelers flock to the island specifically for its many shopping, restaurant, and nightlife options. But back to the views: Hike the Makapuu Lighthouse trail, take in Manoa Falls, explore Waimea Valley…it's a never-ending photo op.
