Things to do in Oahu

Things to do in  Oahu

Welcome to Oahu

This island gem—the third largest of Hawaii’s eight—offers city entertainment to the south and outdoor adventure to the north, just an hour’s drive apart. History buffs can visit Pearl Harbor and the USS Arizona or get a taste of the island at the Polynesian Cultural Center. Experience the outdoors, from snorkeling to sailing to jetskiing to just plain lounging on Waikiki Beach, or with a hike up Diamond Head. And be sure to plan a night at a traditional lu’au; visit to Haleiwa on the North Shore for garlic shrimp and shaved ice; and trip to the Halona Blowhole to snap photos.

Top 15 attractions in Oahu

Pearl Harbor National Memorial

star-4.511,308
Made up of several historic sites and memorials, Pearl Harbor honors and educates the public about the Japanese attack on the United States on December 7, 1941 that propelled the country into World War II. It’s one of Hawaii’s most-visited attractions, and one of the country’s most significant WWII memorial sites.More

Mokolii Island

star-515,074
Located a short distance offshore of Kualoa Point, Mokolii Island is one of Oahu’s most famous landmarks. This small, cone-shaped island attracts adventurous visitors with its secluded coves, rugged hikes, and views of Oahu’s windward coast and the Koolau mountains; the same mountains featured in scenes of the movie Jurassic Park.More

Oahu North Shore

star-521,737
Surfing is king on Oahu’s North Shore, where summer’s placid snorkeling spots are transformed into pounding 40-foot (12-meter) waves come winter. On land you’ll find a peaceful respite from hectic Honolulu, with scenic waterfall hikes, sleepy farms selling tropical fruit, and food trucks doling out garlic shrimp.More

Halona Blowhole

star-528,737
Once visitors are aware that hālona means “lookout” in Hawaiian, it becomes quite clear what the Halona Blowhole is about: views, Pacific Ocean and blowhole! The Halona Blowhole is one of the most spectacular natural wonders on O’ahu Island; the more than 1,000-year-old geyser-like rock formation is characterized by a hole which propels incoming surf in a narrow, molten lava tube, shooting sea spray high into the air as a result - sometimes up to 30 feet. This is mostly a summery phenomenon but wintertime also has a big ticket item drawing visitors: humpback whales. The lookout point offers unobstructed views of the O’ahu shoreline as well as glimpses of Lanai and Moloka'I Islands on clear days.The coast is home to a special type of coral that requires very little light to live, the Sinularia Leather Coral, where it is possible to find various species like echinoderms, slugs, corals, and eels. And although the marine life is quite plentiful and fascinating, divers should proceed with caution because of the strong and sometimes erratic currents, including the colloquially named Moloka'i Express, which can drag divers out to sea without warning. Visitors should know that below the hālona is one of the most dangerous ocean currents in the world, and should always proceed with care.More

Diamond Head

star-522,184
Arguably Hawaii's most well-known sight, Diamond Head Crater is more than just a famous Waikiki backdrop but also an entire attraction unto itself, featuring one of Oahu's best hikes for a panoramic view. From atop the 760-foot (231-meter) summit, visitors can gaze out from Koko Head Crater to the Honolulu skyline and down on Waikiki Beach, where surfers, paddlers, sailboats, and canoes all splash through the tropical waters.More

Dole Plantation

star-529,798
What started out as a Wahiawa fruit stand in the middle of the pineapple fields in 1950 is now an extremely popular Hawaiian attraction. The sprawling Dole Plantation in central Oahu is a rural throwback to a time when the pineapple helped rule Oahu’s economy. Visitors can sample the sweet yellow fruit, ride on the famous Pineapple Express train and motor out through the fields, take a walk through a huge garden maze, learn how to find fresh pineapple when grocery shopping, and hear how pineapples are grown on plants—and not underground or on trees.More

Makapuu Lighthouse

star-512,358
Within Kaiwi State Scenic Shoreline on Oahu’s Windward Coast, the Makapu’u Point Lighthouse Trail is a popular hike ending at the historical red-roofed Makapu’u Lighthouse, built in 1909. Though the lighthouse is not open to the public, the moderately challenging hike attracts travelers and locals alike for its stunning coastal views.More

Waikiki Beach

star-58,717
For decades, Waikiki Beach has been Oahu’s tourist mecca thanks to its palm-fringed white-sand beaches and high-rise luxury hotels that stretch from downtown Honolulu east toward the towering Diamond Head. Here all the spoils of Hawaiian beach life—from sunbathing and swimming to snorkeling and fruity-cocktail sipping—are within steps of world-class shopping and dining.More

Sandy Beach Park

star-511,551
When U.S. President Barack Obama shared that Sandy’s was his favorite Oahu beach early in his presidency, it went from a popular locals’ beach to just plain popular. This public stretch of white sand just north of the extinct Koko Head Crater is no languid oasis, however; it’s one of Oahu’s best—and most intense—spots for bodyboarding and bodysurfing. A fierce shore break best suited for experienced surfers sometimes wells into powerful barrels that can pummel riders trying to catch a wave.The spot is often coupled with a visit to the neighboring Halona Blowhole, a lookout point where waves regularly blow spray up through eroded crevices in the lava rock. And when the wind kicks up, it’s not uncommon to see families flying kites on the spacious lawn fronting the sand.More

USS Arizona Memorial

star-4.514,511
The USSArizona Memorial floats above the watery site where the eponymous battleship was bombed and sunk, taking 1,177 lives with it, in Pearl Harbor on December 7, 1941. The solemn, all-white memorial features a marble wall of names of those who served onboard and spans theArizona’s width, with openings to look down on the sunken hull.More

Hanauma Bay

star-516,996
Hanauma Bay State Park is a protected marine-life-preservation area with clear water ideal for snorkeling and a vast array of tropical fish and coral reefs surrounded by volcanic rock. Once used by the Hawaiian royal family for fishing, it is now one of Oahu’s top tourist destinations with about 1 million visitors each year.More

Tropical Farms Macadamia Nut Farm

star-524,038
Located on the east coast of Oahu, 20 miles (32 kilometers) north of Honolulu, Tropical Farms Macadamia Nuts is set in the shadow of the mountains of the Koolau Range and is a stop on many circle-island tours. It’s a great place to enjoy a Hawaiian treat and shop for gifts and souvenirs.More

Byodo-In Temple

star-515,004
Surrounded by lush grounds, Oahu’s Byodo-In Temple is tucked away in the Kahaluʻu Valley at the foot of the Koʻolau mountain range. A replica of a temple in Japan’s Kyoto Prefecture, the landmark is a testament to the island’s strong Japanese community.More

Nu'uanu Pali Lookout

star-514,234
Oahu’s Nu‘uanu Pali Lookout offers panoramic views of the Ko‘olau Mountains. The windy perch, more than 1,000 feet (300 meters) above Oahu’s Windward (northeast) coastline, also overlooks Kaneohe, Kaneohe Bay, Kailua, and the island of Mokoli‘i. In the late 1700s, the viewpoint was the scene of a bloody battle won by King Kamehameha I.More

Battleship Missouri Memorial

star-57,642
Nicknamed the “Mighty Mo,” the USS Missouri—now known as the Battleship Missouri Memorial—is the site where the Japanese signed the surrender documents that ended World War II, on September 2, 1945. The ship is now a museum and a memorial to the war’s conclusion.More

People Also Ask

What should you not miss on Oahu?

Most visitors to Oahu head straight for Waikiki Beach, but once you’ve soaked up the scene there, you should make time for the beaches along the North Shore and Lanikai on the slower paced west coast. Snorkeling in Hanauma Bay is a must, as is hiking up Diamond Head.

...More
What is there to do in Oahu besides the beach?

You can dive into the cultural history of the Hawaiian Islands by visiting the Bishop Museum and Iolani Palace, which was home to the Hawaiian monarchy. History buffs should also visit Pearl Harbor and the USS Arizona and keen hikers should follow the trails to the Makapuʻu Lighthouse, Lanikai Pillboxes, and Manoa Falls.

...More
Are Honolulu and Oahu the same?

No. While the words are sometimes used interchangeably, Honolulu is the name of the capital of, and largest city in, the US state of Hawaii. Honolulu is located on Oahu, which is one of the eight main islands of Hawaii—the others are Maui, Kauai, Lanai, Molokai, Kahoolawe, Nihau, and the Island of Hawaii (“Big Island”).

...More
What do locals do on Oahu?

A favorite thing to do is to grab some snacks from a local Foodland supermarket and spend a day with friends on the beach—though typically not on the crowded beaches such as Waikiki. On the first Friday of the month, the Honolulu Arts District and Chinatown host a street festival filled with art, music, and food and drink specials.

...More
Why is Oahu so popular?

Oahu holds a place in travelers imaginations because, for so long, it has been immortalized in travel brochures and movies. For better or worse, Oahu—with its beautiful beaches and swaying palm trees— is the embodiment of the tropical island paradise so many travelers are looking for.

...More
What is the prettiest part of Oahu?

Above the white sands of Lanikai Beach, Kaiwa Ridge, or the Lanikai Pillbox Hike, offers some of the best views on Oahu. From the top of the trail you’ll be rewarded with sweeping views of the Windward Coast, over its deep blue water and offshore islands, to Chinaman’s Hat and Waimanalo.
