Oahu

Oahu is one-stop Hawaii—all the allure of the Islands in a plate-lunch mix that has you kayaking around offshore islets by day and sitting in a jazz club 'round midnight, all without ever having to take another flight or repack your suitcase. It offers both the buzz of modern living in jam-packed Honolulu (the state's capital) and the allure of slow-paced island life on its northern and eastern shores. It is, in many ways, the center of the Hawaiian universe.

There are more museums, staffed historic sites, and guided tours here than you'll find on any other island. And only here do a wealth of renovated buildings and well-preserved neighborhoods so clearly spin the story of Hawaii's history. It's the only place to experience Islands-style urbanity, since there are no other true cities in the state. And yet you can get as lost in the rural landscape and be as laid-back as you wish.

Oahu is home to Waikiki, the most famous Hawaiian beach, as well as some of the world's most famous surf on the North Shore, and Hawaii's best-known historical site—Pearl Harbor. If it's isolation, peace, and quiet you want, Oahu might not be for you, but if you'd like a bit of spice with your piece of paradise, this island provides it.

Encompassing 597 square miles, Oahu is the third-largest island in the Hawaiian chain. Scientists believe the island was formed about 4 million years ago by three shield volcanoes: Waianae, Koolau, and the recently discovered Kaena. Recognized in mid-2014, Kaena is the oldest of the three and has long since been submerged 62 miles from Kaena Point on Oahu's northwestern side. Waianae created the mountain range on the western side of the island, whereas Koolau shapes the eastern side. Central Oahu is an elevated plateau bordered by the two mountain ranges, with Pearl Harbor to the south. Several of Oahu's most famous natural landmarks, including Diamond Head and Hanauma Bay, are tuff rings and cinder cones formed during a renewed volcanic stage (roughly 1 million years ago).

The northern and eastern sides of Oahu—and of each Hawaiian island—are together referred to as the Windward side, and generally have a cooler, wetter climate. The island's southern and western sides are commonly called the Leeward side, and are typically warmer and more arid. The island's official flower, the little orange ilima, grows predominantly in the east, but lei throughout the island incorporate ilima. Numerous tropical fish call the reef at Hanauma Bay home, migrating humpback whales can be spotted off the coast past Waikiki and Diamond Head December–April, spinner dolphins pop in and out of the island's bays, and the 15 islets off Oahu's eastern coast provide refuge for endangered seabirds.

Oahu is the most visited Hawaiian island because early tourism to Hawaii started here. It's also the most inhabited island today—69% of the state's population lives on Oahu—due to job opportunities and the island's military bases. Although Kilauea volcano on Hawaii was a tourist attraction in the late 1800s, it was the building of the Moana Hotel on Waikiki Beach in 1901 and subsequent advertising of Hawaii to wealthy San Franciscans that really fueled tourism in the Islands. Oahu was drawing tens of thousands of guests yearly when, on December 7, 1941, Japanese Zeros appeared at dawn to bomb Pearl Harbor. Though tourism understandably dipped during the war (Waikiki Beach was fenced with barbed wire), the subsequent memorial only seemed to attract more visitors, and Oahu remains hugely popular with tourists—especially the Japanese—to this day.

  • 1. Ala Moana Regional Park

    Ala Moana

    A protective reef makes Ala Moana essentially a ½-mile-wide saltwater swimming pool. Very smooth sand and no waves create a haven for families and stand-up paddleboarders. After Waikiki, this is the most popular beach among visitors, and the free parking area can fill up quickly on sunny weekends. On the Waikiki side is a peninsula called Magic Island, with shady trees and paved sidewalks ideal for jogging. Ala Moana Regional Park also has playing fields, tennis courts, and a couple of small ponds for sailing toy boats. The beach is for everyone, but only in the daytime; after dark, it's a high-crime area, with many unhoused people. Amenities: food and drink; lifeguards; parking (free); showers; toilets. Best for: swimming; walking.

  • 2. Bellows Field Beach Park

    Bellows is the same beach as Waimanalo, but it's under the auspices of the military, making it more friendly for visitors—though that also limits public access on weekends. The park area is excellent for camping, and ironwood trees provide plenty of shade. There are no food concessions, but McDonald's and other takeout options are right outside the entrance gate; there's also a weekend farmers' market. The beach is best before 2 pm. After 2, trade winds bring clouds that get hung up on steep mountains nearby, causing overcast skies. Amenities: lifeguards; parking (no fee); showers; toilets. Best for: solitude; swimming; walking.

  • 3. Bishop Museum

    Kalihi

    Founded in 1889 by Charles R. Bishop as a memorial to his wife, Princess Bernice Pauahi Bishop, the museum began as a repository for the royal possessions of this last direct descendant of King Kamehameha the Great. Today, it's the state's designated history and culture museum. Its five exhibit halls contain almost 25 million items that tell the history of the Hawaiian Islands and their Pacific neighbors. Gain understanding of the entire region in the Pacific Hall, and learn about the culture of the Islands through state-of-the-art and often-interactive displays in the Hawaiian Hall. Spectacular artifacts—lustrous feather capes, bone fishhooks, the skeleton of a giant sperm whale, photography and crafts displays, and a well-preserved grass house—are displayed inside a three-story, 19th-century, Victorian-style gallery. The building alone, with its huge turrets and immense stone walls, is worth seeing. In the 16,500-square-foot science adventure wing, it's hard to miss the three-story simulated volcano where regular "lava melts" take place to the delight of younger (and young at heart) visitors. Also check out the planetarium, daily tours, lauhala-weaving and science demonstrations, special exhibits, the Shop Pacifica, and the Bishop Museum Café, which serves ono (delicious) Hawaiian food by local restaurant Highway Inn.

  • 4. Byodo-In Temple

    Tucked away in the back of the Valley of the Temples Memorial Park is a replica of the 11th-century temple at Uji in Japan. A 2-ton, carved-wood statue of the Buddha presides inside the main building. Next to the temple are a meditation pavilion and gardens set dramatically against the sheer, green cliffs of the Koolau Mountains. You can ring the 5-foot, 3-ton brass bell for good luck; feed some of the hundreds of koi, ducks, and swans that inhabit the garden's 2-acre pond (buy fish food at the gift shop); and relax and enjoy the peaceful surroundings. Call ahead to schedule a guided tour.

  • 5. Diamond Head State Monument

    Diamond Head

    Panoramas from this 760-foot extinct volcanic peak, once used as a military fortification, extend from Waikiki and Honolulu in one direction and out to Koko Head in the other, with surfers and windsurfers scattered like confetti on the cresting waves below. The 360-degree perspective is a great orientation for first-time visitors. On a clear day, look east past Koko Head to glimpse the outlines of the islands of Maui and Molokai. To enter the park from Waikiki, take Kalakaua Avenue east, turn left at Monsarrat Avenue, head a mile up the hill, and look for a sign on the right. Drive through the tunnel to the inside of the crater. The ¾-mile trail to the top begins at the parking lot. Be aware that the hike up to the crater has numerous stairs to climb; if you aren't in the habit of getting occasional exercise, this might not be for you. At the top, you'll find a somewhat awkward scramble through a tunnel and bunker out into the open air, but the view is worth it. As you walk, note the color of the vegetation: if the mountain is brown, Honolulu has been without significant rain for a while, but if the trees and undergrowth glow green, you'll know it's the wet season (winter) without looking at a calendar. Winter is when rare Hawaiian marsh plants revive on the floor of the crater. Wear a hat and take bottled water with you to stay hydrated under the tropical sun as there are no water stations (or any shade) along the hike. Keep an eye on your watch if you're here at day's end: the gates close promptly at 6 pm. To beat the heat and the crowds, rise early and make the hike before 8 am.

  • 6. Fort DeRussy Beach Park

    Waikiki

    A wide, soft, ultra-white shore with gently lapping waves makes this fine beach a family favorite for running-jumping-frolicking fun. Other bonuses include the shaded, grassy grilling area, the sand volleyball courts, and the many aquatic rental options. The beach fronts the Hale Koa Hotel as well as Fort DeRussy. Amenities: food and drink; lifeguards; showers; toilets; water sports. Best for: swimming; walking.

    2161 Kalia Rd., Honolulu, Hawaii, 96815, USA
  • 7. Haleiwa Alii Beach Park

    The winter waves are impressive here, but in summer, the ocean is like a lake, ideal for family swimming. The beach itself is big and tends to be full of locals. Its broad lawn off the highway is often the site of volleyball and Frisbee games, family barbecues, and art festivals and carnivals. This beach is also the opening break for the Triple Crown of Surfing. Amenities: lifeguards; parking (no fee); showers; toilets. Best for: surfing; swimming.

    66-167 Haleiwa Rd., Haleiwa, Hawaii, 96712, USA
  • 8. Halona Blowhole

    Below a scenic turnout along the Koko Head shoreline, this oft-photographed lava tube sucks the ocean in and spits it out. Don't get too close, as conditions can get dangerous. Look to your right to see the tiny beach below that was used to film the wave-washed love scene in From Here to Eternity. In winter, this is a good spot to watch whales at play. Offshore, the island of Molokai calls like a distant siren, and, every once in a while, Lanai is visible in blue silhouette. Take your valuables with you, and lock your car, because this popular scenic location is a hot spot for petty thieves.

  • 9. Hanauma Bay Nature Preserve

    Picture this as the world's biggest open-air aquarium. You come to see fish, and fish you'll see. Due to their exposure to thousands of visitors every week, these fish are more like family pets than the skittish marine life you might expect. An old volcanic crater has created a haven from the waves where the coral has thrived. Note that there's a fee for nonresidents to enter the preserve; make reservations and prepay online ahead of time. You must also watch a nine-minute video about the nature preserve in its educational center before being allowed down to the bay. Snorkel equipment and lockers are available for rent, and you can walk the short distance from the parking lot or take a tram.  It's best to visit early in the morning (around 7), as it's difficult to park later in the day. Need transportation? Take TheBus each way from anywhere on the island. Amenities: food and drink; lifeguards; parking (fee); showers; toilets. Best for: snorkeling; swimming.

  • 10. Honolulu Museum of Art

    Downtown

    Originally built around the collection of a Honolulu matron who donated much of her estate to the museum, the Honolulu Academy of Arts is housed in a maze of courtyards, cloistered walkways, and quiet, low-ceiling spaces. There's an impressive permanent collection that includes the third-largest assembly of Hiroshige's ukiyo-e Japanese prints in the country (donated by author James Michener); Italian Renaissance paintings; and American and European art by Monet, van Gogh, and Whistler, among many others. The newer Luce Pavilion complex, nicely incorporated into the more traditional architecture of the museum, has a traveling-exhibit gallery, a Hawaiian gallery, an excellent café, and a gift shop. The Doris Duke Theatre screens art films. This is also the jumping-off point for tours of Doris Duke's striking estate, which is now the Shangri La Museum of Islamic Art, Culture, and Design. If you wish to visit, you should reserve tickets well in advance.

  • 11. Hoomaluhia Botanical Garden

    The name, which means "a peaceful refuge," describes the serenity and feeling of endless space you find in this verdant garden framed by the stunning Koolau Range. Its 400 acres contain specimens from such tropical areas as the Americas, Africa, Melanesia, the Philippines, and Hawaii. Not just for the botanist, Hoomaluhia also has a 32-acre lake, easy walking trails, and open lawns ideal for picnicking and camping by permit. Families can also take advantage of the park's catch-and-release tilapia fishing program; free bamboo fishing poles are sometimes available for borrowing at the visitor center. If you see unusually dressed-up visitors, they are likely selfie seekers doing it for the 'gram. Hoomaluhia is very photogenic; just make sure you're not blocking the roadways in search of the perfect shot.

  • 12. Iolani Palace

    Downtown

    America's only official royal residence, on the site of an earlier palace, was completed in 1882. It contains the thrones of King Kalakaua and his successor (and sister) Queen Liliuokalani. Bucking the stereotype of simple island life, the palace had electric lights even before the White House. Downstairs galleries showcase the royal jewelry, as well as a kitchen and offices that have been restored to the glory of the monarchy. The palace gift shop and ticket office are now in what was formerly the Iolani Barracks, built to house the Royal Guard. The palace has self-guided audio tours and guided tours. Guided tours are only available in the mornings, and it's best to make reservations a few days in advance.

  • 13. Kailua Beach Park

    A cobalt-blue sea and a wide continuous arc of powdery sand make this one of the island's best beaches, as illustrated by the crowds of local families who spend their weekend days here. The water is calm, a line of palms and ironwoods provides shade on the sand, and a huge park has picnic pavilions where you can escape the heat. This is also the "it" spot for windsurfing or kiteboarding, and you can rent kayaks nearby at Kailua Beach Adventures ( 130 Kailua Rd.) for day trips to the Mokulua Islands. Amenities: lifeguards; parking (no fee); showers; toilets; water sports. Best for: swimming; walking; windsurfing.

    437 Kawailoa Rd., Kailua, Hawaii, 96734, USA
  • 14. Ko Hana Distillers

    Polynesians brought sugarcane to Hawaii more than 1,000 years ago, long before plantations were established on the Islands in the 1800s. Ko Hana grows 34 varieties of heirloom sugarcane and harvests it all by hand, then presses and distills the juice to make small-batch pure-cane rums. Stop by the tasting room at the farm in rural Kunia near Wahiawa, in the heart of the central valley for tastings. Standouts include Koho, a barrel-aged rum, and Kokoleka, made with pure cacao and raw honey. Sign up in advance for tours, which happen daily every hour until 4 pm and include a side-by-side tasting of white and barrel-aged rums. For a more in-depth experience, reserve a spot on a farm tour (Thursday morning at 10) and sample canes as well as rums.

  • 15. Ko Olina Beach

    This is the best spot on the island if you have small kids. The resort area commissioned a series of four man-made lagoons, but, as it has to provide public beach access, you are the winner. Huge rock walls protect the lagoons, making them perfect spots for the kids to get their first taste of the ocean without getting bowled over. The large expanses of seashore grass and hala trees that surround the semicircle beaches are made-to-order for nap time. A 1½-mile jogging track connects the lagoons. Due to its appeal for keiki (children), Ko Olina is popular, and the parking lot fills up quickly when school is out and on weekends, so try to get here before 10 am. The biggest parking lot is at the farthest lagoon from the entrance. There are actually three resorts here: Aulani (the Disney resort), Four Seasons Resort Oahu, and the Marriot's Ko Olina Beach Club (which has a time-share section as well). Amenities: food and drink; parking (no fee); showers; toilets. Best for: sunset; swimming; walking.

  • 16. Kualoa Ranch

    Encompassing 4,000 acres, about 45 minutes by car from Waikiki, this working ranch offers a wide range of activities—from ATV and horseback tours to zip-lining or expeditions into the valley on an electric bike. The mountains that serve as the backdrop here may seem familiar: the ranch has served as the set for movies such as Jurassic Park and Windtalkers, as well as TV shows like Magnum P.I. and Lost (and you can take a film sites tour). From the grounds, you'll have a wonderful view of the ocean and Mokolii (Chinaman's Hat). You can drop by the visitor center anytime, but it's best to book activities and tours two or three days in advance.

  • 17. Kualoa Regional Park

    Grassy expanses border a long, narrow stretch of sand with spectacular views of Kaneohe Bay and the Koolau Mountains, making Kualoa one of the island's most beautiful picnic, camping, and beach areas. Dominating the view is an islet called Mokolii, better known as Chinaman's Hat, which rises 206 feet above the water. You can swim in the shallow areas of this rarely crowded beach year-round. The one drawback is that it's usually windy here, but the wide-open spaces are ideal for kite flying. Amenities: lifeguards; showers; toilets. Best for: solitude; swimming.

    49-479 Kamehameha Hwy., Kaaawa, Hawaii, 96744, USA
  • 18. Lanikai Beach

    Think of the beaches you see in commercials: peaceful jade-green waters, powder-soft white sand, families and dogs frolicking, and offshore islands in the distance. It's an ideal spot for camping out with a book. Though the beach hides behind multimillion-dollar houses, by state law there is public access every 400 yards. Street parking is available but very difficult to find (and prohibited on holiday weekends). Consider parking at Kailua Beach Park and walking along the paved pathway into Lanikai. Just don't block the boat ramp stalls. There are no shower or bathroom facilities here—but you'll find both at Kailua Beach Park. Look for walled or fenced pathways every 400 yards, leading to the beach. Be sure not to park in the marked bike/jogging lane.Amenities: none. Best for: sunrise; swimming; walking.

  • 19. Makapuu Point

    This spot has breathtaking views of the ocean, mountains, and the windward Islands. The point of land jutting out in the distance is Mokapu Peninsula, site of a U.S. Marine base. The spired mountain peak is Mt. Olomana. On the long pier is part of the Makai Undersea Test Range, a research facility that's closed to the public. Offshore is Manana Island (Rabbit Island), a picturesque cay said to resemble a swimming bunny with its ears pulled back. Ironically enough, Manana Island was once overrun with rabbits, thanks to a rancher who let a few hares run wild on the land. They were eradicated in 1994 by biologists who grew concerned that the rabbits were destroying the island's native plants. Nestled in the cliff face is the Makapuu Lighthouse, which became operational in 1909 and has the largest lighthouse lens in America. The lighthouse is closed to the public, but near the Makapuu Point turnout you can find the start of a paved mile-long road (it's closed to vehicular traffic). Hike up to the top of the 647-foot bluff for a closer view of the lighthouse and, in winter, to do some whale-watching.

    Kalanianaole Hwy., Waimanalo, Hawaii, 96825, USA
  • 20. Nuuanu Pali State Wayside

    This panoramic perch looks out to expansive views of Windward Oahu—from Kaneohe Bay to a small island off the coast called Mokolii ("little lizard," also known as Chinaman's Hat). It was in this region that King Kamehameha I drove defending forces over the edges of the 1,200-foot-high cliffs, thus winning the decisive battle for control of the island. Temperatures at the summit are several degrees cooler than in warm Waikiki, so bring a jacket along. Hang on tight to any loose possessions, and consider wearing pants; it gets extremely windy at the lookout, which is part of the fun. After arriving in the pay-to-park lot, remove valuables from your car and lock it; break-ins have occurred here (this wayside is in the most trafficked state park in Hawaii).
