Things to Do in Oahu: Top Attractions, Activities, and Hidden Gems

Oahu was the last of the four main Hawaiian islands I visited. I was worried it would feel too “big city” and not enough “tropical island” for my liking. But I was wrong. Sure, there are high rises on the beach and large shopping centers. But Oahu offers so much more than that.

Oahu, known as “The Gathering Place,” is a stunning Hawaiian island filled with natural beauty, rich culture, and endless adventure. Whether you’re looking for outdoor thrills, historic landmarks, or the best beaches to relax on, Oahu has something for everyone. Here’s a guide to the best things to do in Oahu.

Things to do in Oahu – Explore the Beaches like Waikiki Beach

Oahu is home to some of the most picturesque beaches in the world. And they’re also some of the most fun things to experience on Oahu. Whether you want to surf, snorkel, or simply bask in the sun, there’s a beach for you. Below, you’ll find a few of my favorite beach spots. Or you can check out this full list of the best beaches in Oahu.

• Waikiki Beach – Perfect for first-time visitors, this famous beach offers soft sand, clear waters, and plenty of dining and shopping nearby. Plus, there are many hotels, restaurants, surf shops, and boat rides within walking distance, and the views of the Waikiki skyline make it so much fun at sunset.
• Lanikai Beach – Known for its powdery white sand and turquoise waters, this is an ideal spot for kayaking and stand-up paddleboarding. And its calm water is especially good for young kids and families. It’s also totally free to enjoy, though having a rental car makes it easier to reach along the east side.

Kayaking to the Mokulua Islands is also a popular activity from this area.

• Sunset Beach – A great place to enjoy a peaceful swim in the summer. But winter brings big waves, huge waves, and a dangerous shore break best left to experienced surfers.
• Laniakea Beach – One of the best spots on Oahu’s North Shore to see sea turtles. Watch for turtles swimming or resting on shore from a respectful distance.

Visit Historic Landmarks like Pearl Harbor

Oahu is steeped in history, from ancient Hawaiian culture to pivotal World War II sites.

• Pearl Harbor National Memorial – Pay your respects and learn about the history of the USS Arizona Memorial and other key sites from WWII. I feel like this is an absolute must-do in Oahu, at least once. The onsite gift shop is also a convenient stop if you want a souvenir after your visit.
• Iolani Palace – The only royal palace in the United States, offering a fascinating glimpse into Hawaii’s monarchy and deeper Hawaiian history.
• Byodo-In Temple – A peaceful, stunning temple set against the backdrop of the lush Ko’olau Mountains.

Go on an Outdoor Adventure

Oahu’s diverse landscape and Hawaiian history, along with its World War II sites, make it a paradise for adventure lovers.

Hike Diamond Head & Plus Other Popular Trails

A must-do for first-time visitors, many travelers plan to hike up Diamond Head for panoramic views of Honolulu and the Pacific Ocean. This out and back trail is commonly described as a 1.6-mile round trip hike, though it is also often listed as 1.8 miles with 452 feet of elevation gain. There is an entrance fee plus a reservation requirement for out-of-state visitors, and one steep climb near the end is the toughest part of the entire hike. Be sure to wear proper hiking shoes. If you book a tour, your reservation is included.

If you want more hiking ideas, Makapu’u Point Lighthouse Trail is fairly easy at 2.5 miles with 500 feet of elevation gain. Lanikai Pillbox is a 0.9-mile roundtrip option for catching sunrise and a beautiful sunrise. Lulumahu Falls is 1.8 miles roundtrip, and Koko Crater Tramway Trail climbs 885 feet. The Wiliwilinui Ridge trail is another solid day-hike choice with great views. If you’re considering the crouching lion hike, know that the lion hike is scenic but more challenging and exposed than these other options. For all the details, check individual hike guides.

Kualoa Ranch – One of the most popular things to do in Oahu

Take an ATV or horseback ride through the scenic landscapes where famous movies like Jurassic Park were filmed, or choose one of the family-friendly movie set tours. Their horseback tours are especially popular, so booking ahead is smart.

Shark Cage Diving in Haleiwa –

For thrill-seekers, get up close and personal with sharks in their natural habitat. This is one of the most memorable shark tours on Oahu, with cage and cageless options available through different operators. This one is so cool! Scary, but cool.

Things to do in Oahu – Experience Hawaiian Culture at the Polynesian Cultural Center

Immerse yourself in the local culture by attending events and tasting authentic Hawaiian cuisine.

• Attend a Luau – A traditional luau typically includes Hawaiian music, hula, cultural performances, and a buffet dinner at spots like Paradise Cove or the Polynesian Cultural Center.
• Try Local Food – Don’t miss out on Hawaiian favorites like poke, loco moco, and malasadas at iconic spots like Giovanni’s Shrimp Truck, Foodland for some of the best poke in Oahu, and Leonard’s Bakery, which has been serving malasadas since 1952. For breakfast or a snack, Sunrise Shack is a popular stop for acai bowls, fresh juices, and other delicious food. Also, try shave ice–it’s a must!
• Explore Chinatown – A great place to try local markets, sample fusion cuisine, and experience Oahu’s vibrant nightlife, with downtown Honolulu and Shirokiya Japan Village Walk also nearby for a variety of Japanese cuisine.

Things to do in Oahu – Enjoy Water Activities

The crystal-clear waters surrounding Oahu provide endless opportunities for aquatic fun.

• Snorkel at Hanauma Bay – One of the best snorkeling spots in Hawaii, Hanauma Bay Nature Preserve offers colorful coral reefs and diverse marine life in a protected setting; bringing your own snorkel gear, water shoes, and other snorkeling gear can make the visit easier.
• Go Whale Watching – Visit in the winter months, and I highly encourage booking with experienced tour operators since most tours are designed to help you spot humpback whales.
• Take a Surf Lesson – Oahu is the birthplace of surfing, and Waikiki Beach is the perfect place to learn; a one hour lesson is a good minimum, and for many first-timers it becomes such an incredible experience.
• Take a sunset cruise – It lasts about 2 hours, offers gorgeous golden hour views, and takes only a few hours out of the day.
• Snorkel at Turtle Canyon – This is a popular spot for reliable sea turtle sightings, and you may even see turtles swimming nearby. If you want another turtle-focused area, Turtle Bay on the North Shore is also a scenic place to explore.

Discover the North Shore

Oahu’s North Shore is about an hour from Waikiki and is one of the island’s most iconic regions, known for its laid-back vibe, stunning beaches, and world-class surfing.

• Visit Waimea Valley – A lush botanical garden with a beautiful waterfall where you can swim.
• Stop at Waimea Bay – In summer, Waimea Bay is calmer for swimming, but winter surf can be dangerous, with strong shore break. In calmer conditions, some visitors also come for cliff jumping.
• Watch Surfing Competitions – If you visit in the winter, watch top surfers tackle the big waves at Pipeline and Sunset Beach, where huge waves make this stretch famous.
• Taste Shrimp from Food Trucks – Giovanni’s Shrimp Truck is a must-stop for delicious garlic shrimp plates, and Haleiwa is also a fun stop for local food and shave ice. You can also try a north shore food truck for other casual bites, grab acai bowls at sunrise shack, or stop by the dole plantation for dole whip on the way. Limited street parking and a busy parking lot can affect some popular stops.

Relax and Enjoy Resort Amenities

Oahu is home to world-class resorts offering luxurious amenities and activities for a relaxing getaway. And nearby resort areas also keep families close to fun things in Waikiki and other activity hubs for a memorable Hawaiian vacation. If you’re traveling with the kids, check out this list of the best family resorts in Oahu that are sure to provide plenty of entertainment for the whole family. You’ll find iconic Waikiki stays like the Royal Hawaiian within walking distance of the beach.

• Indulge in a Spa Day – Many resorts offer spa treatments featuring traditional Hawaiian techniques and ingredients.
• Lounge by the Pool – Unwind at infinity pools with ocean views or family-friendly water parks at resorts like Aulani, A Disney Resort & Spa
• Enjoy Resort Activities – Participate in cultural programs, yoga classes, and beachfront luaus without leaving the property, and consider the Polynesian Cultural Center for interactive cultural activities for kids.
