After six long hours on a plane, you're dying to collapse on the nearest Oahu beach. Don't get me wrong, that beach is a work of beauty. But Honolulu has plenty more to offer than crystal blue waves and pale yellow sand.
Diamond Head
Positioned at the far end of Waikiki, Diamond is easily reached by any of the major hotels on the southern shore. One of the gentlest hikes on Oahu, the crater peak rewards you with a stellar view of Honolulu. There are also a number of scenic viewpoints surrounding the crater, including a view of the famous Black Point, where you can catch a glimpse of one of Doris Duke's elaborate homes.
Honolulu Museum of Art
If you want to actually visit Doris Duke's Shangri-La, you have to sign up for a guided tour with the Honolulu Museum of Art. The tour starts from the museum, which sits across from St. Thomas Square, a park with its very own enormous banyan tree. You are shuttled to and from Shangri-La, after which you can cruise through the museum at your own pace. Don't miss the incredible collections of Near Eastern and Pacific art.
Iolani Palace
For a more historical tour, visit Iolani Palace, the official residence of Hawaii's deposed monarchy. Once featured as the base of operations in the original Hawaii Five-O, the actual palace is a stunning monument of stone and grandeur. Guided tours are held at regularly scheduled hours, but it's possible to wander the grounds independently as well.
Pearl Harbor
Some distance outside the city--though not far at all, by mainland standards--sits Pearl Harbor. Here, you can pay your respects at the submerged U.S.S. Arizona Memorial, or venture on board the U.S.S. Bowfin, a submarine museum that allows you to explore the vessel from top to bottom.
Japanese Cultural Center
Located near to the University of Hawaii, the Japanese Cultural Center always has interesting exhibits showcasing the past of Hawaii's Japanese immigrants. Many Japanese families have been American citizens for four or five generations, and their contribution to the state's history is a fascinating tale.
The Hawaii Nature Center
Sitting in the back of Manoa Valley, right at the beginning of Manoa Trail, the Hawaii Nature Center is a must-see for anyone who wants to get in touch with the natural side of the islands. Surrounded by a thick rain forest, the Nature Center is geared toward education. It's the perfect place for families, but the nearby hiking is great for all ages.
Hanauma Bay
In the opposite direction of Pearl Harbor lies Hanauma Bay. A crater that has been hollowed out by the sea, the rich volcanic earth sustains a colorful coral reef. Visitors are welcome to swim with the marine life, but cautioned not to touch the coral or feed the animals. The protected position of the bay keeps sharks away, but has made it a home for turtles.
