15 of the Top Things To Do on Oahu Per Viator Travelers

What?: A luau is a traditional Native Hawaiian feast and is one of the top Oahu activities. The Native Hawaiian–owned Toa Luau at Waimea Valley is about as authentic as it gets—outside of a family backyard luau, of course. A luau experience not only includes the traditional dance performances, but food, cocktails, the chance to explore the botanical gardens, and hiking to Waimea Falls as well.

When?: Toa Luau offers two show times: one around lunch and one in the late afternoon.

What one reviewer said: “Toa Luau was incredible. It was very interactive, captivating and full of learning and cultural experiences. Hands down, would recommend. Cast and crew were exceptionally talented and extremely kind and helpful.” Sarah_M, March 2025

What?: On December 7, 1941, the Japanese military bombed the base at Pearl Harbor, prompting the US to join World War II. History buffs won’t want to miss the chance to tour the Pearl Harbor National Memorial—one of the top attractions on Oahu—where various exhibits and memorials honor those who lost their lives that day.

When?: An early morning visit is best to avoid the crowds. Reservations are strongly recommended to guarantee entry.

What one reviewer said: “Clift was a great local guide who provided information and an educational experience on the history of Hawaii. He also gave great instruction [on] when/where to meet and board the van. The tour was perfect and [gave] just enough time to absorb this pivotal time in history without feeling too overwhelmed!” Victoria_C, February 2025

What?: Without a doubt, Diamond Head is the most famous landmark on Oahu. Book a hike to the top of this volcanic crater for epic views of Waikiki, Honolulu, and the Pacific Ocean. You can even customize your excursion to ascend the crater at your own pace.

When?: Like with most Hawaii hikes, you’ll want to get an early start to beat the heat and the crowds.

What one reviewer said: “We got up very early for this and the morning was comfortable and not crowded. The climb is not bad and you can do it round trip in 2 hours easy! Highly recommend. The views are stunning.” Howard_R, February 2025

What?: Nestled within the beautiful Ko’olau Mountains of Kaʻaʻawa Valley, Kualoa Ranch features a stunning natural landscape. These oceanfront mountains have caught many Hollywood directors’ eyes, and quite a few big-name movies have been filmed here, most notably the Jurassic Park franchise. Movie tours will take you to the locations you might recognize from the silver screen.

When?: There are plenty of Kualoa Ranch tour times, although it’s best to book at least a few days in advance during peak season.

What one reviewer said: “This was so much more than a movie site tour! Koa’s passion for the beautiful nature preserve and ranch’s history shone through as he guided our tour. Ask him to take your favorite vacation photo and you won’t be disappointed!” Nancy_B, December 2024

What?: Located in Kaneohe under the shade of the striking Koolau Mountains, the Byodo-In Temple on Oahu is a miniature version of a 1,000-year-old temple of the same name in Uji, Japan. Full-day tours include a stop here to wander its peaceful grounds, before heading to more Oahu tourist spots.

When?: Try to visit the temple soon after its morning opening time for the most peaceful experience.

What one reviewer said: “We were wanting to see different parts of Oahu and this didn't disappoint! We had plenty of time to stretch our legs and get pictures at each site. Ian, our guide, was knowledgeable and personable, and we were so lucky to have him!’ Lisa_P, March 2025

What?: Oahu’s west coast offers incredible snorkeling—you may spot turtles, fish, rays, and more beneath the water’s surface. Snorkeling excursions take you to the island’s best spots for marine life, while some offer the chance to swim alongside dolphins— a magical experience that you won’t forget anytime soon.

When?: While tours are often offered throughout the day, early morning can be the best time to see wild dolphins.

What one reviewer said: “What an incredible experience! This was my boyfriend and [my] favorite excursion in Oahu. We were able to swim with dolphins and even had a pod of whales cross the front of our boat! The crew made this trip so fun—very funny and friendly! I couldn’t recommend this excursion more.” Tristin_S, February 2025

What?: The Waikiki open-air trolley has been a long-time staple of the tourist hub. Many trolleys use the popular hop-on hop-off method, allowing you to visit major Oahu tourist spots in Waikiki and Honolulu at your own pace. Simply put, it’s an easy and convenient way to do some Oahu sightseeing.

When?: The Waikiki hop-on hop-off trolley has different timetables for each route; most start in the morning and finish by mid-afternoon.

What one reviewer said: “Great location. Awesome driver. Very knowledgeable about the area. Very convenient. Trip took 2 hours from start to finish. We stayed on the whole time. Great way to see parts of Honolulu without a vehicle.” robert_d, January 2025

What?: Hawaii has a truly unique food scene, with influences from Native Hawaiian dishes, a variety of immigrant cuisines, and local produce. One of the best things to do on Oahu is to take a food tour to dive into this unique culinary world, trying everything from manapua (a type of bao buns) to poke and fresh fruits.

When?: There’s no bad time to eat your way around the island, just plan to arrive hungry.

What one reviewer said: “This tour exceeds any expectations! Victor is so friendly and knowledgeable about many cultures and made the experience 100% worth it! The cuisines were so unique and fun to try and we even got to take some home.” KayLynn_B, March 2025

What?: It’s worth making time in your Oahu itinerary to learn about the island’s fascinating Native Hawaiian culture and history: It’s the foundation of what makes it so special, after all. Downtown Honolulu is home to several historic landmarks, including Ali'iolani Hale, Iolani Palace, and the Kawaiaha'o Church. You can visit them all in one go on a walking tour of the city.

When?: There’s no bad time to visit these must-see places on Oahu, but slots on walking tours can be limited, so check ahead.

What one reviewer said: “It was very informative with interesting facts and stories told by our knowledgeable tour guide, Susan. She was fun, friendly, and full of great anecdotes and facts that held everyone's interest.” Maria_B, January 2025

What?: Hawaiian sunsets are famed for their beauty, and while you can enjoy them on land, sunset sailing tours can offer particularly memorable views. Many boat excursions sail out of Waikiki or Honolulu and past the island's landmarks. Plus, you might spot marine life, including whales and dolphins.

When?: There really is no bad time of year to enjoy a sunset cruise on Oahu.

What one reviewer said: “We had an amazing time! Everyone was kind. The drinks were delicious. Music was good. We had an opportunity to see whales while watching the sunset.” Maderica_B, February 2025

What?: While coffee beans tend to be associated with Hawaii, a new bean is coming on the scene: the cacao bean. Take a deep dive into the cacao-growing industry and the chocolate-making process on a Kamananui Cacao Orchard tour. Those with a sweet tooth will be happy to hear that samples are included, too.

When?: Farm tours are usually available from Monday to Wednesday, Friday, and Saturday, with multiple tour times each day.

What one reviewer said: “This was a great and informative tour! Chari was a fun and bubbly guide and we learned a lot from Max. It was great trying the cacao and taste testing chocolate from Manoa. Definitely recommend!” Sofia_A, January 2025

What?: The Mokulua Islands—locally called the Mokes—are a pair of picturesque islands about 0.75 miles (1.2 kilometers) from Lanikai Beach and 2.5 miles (4 kilometers) from Kailua Beach. You can put your paddling skills to work on a kayaking adventure—but don't worry, these waters are relatively calm.

When?: You need a permit to kayak to the Mokes, but it’s easy enough to get this from any kayak rental place; just note that permits can’t be issued on Sundays.

What one reviewer said: “Wow! What a magical experience! We saw turtles during the paddle to the twin islands and a monk seal joined us on the beach. Our guide (Riki) was very knowledgeable and friendly and took us to a secret pool reserved for royalty. We had time to snorkel before heading back. Definitely an adventure not to be missed.” Rachel_C, March 2025

What?: While most of Oahu is accessible by car, the island looks completely different from the air on a helicopter trip. Spot popular sights including Diamond Head and Pearl Harbor, plus others you can only see from the air, such as Sacred Falls.

When?: Try to schedule your helicopter tour early in your trip: If the tour needs to be cancelled due to inclement weather, this will give you more rescheduling options.

What one reviewer said: “We were in Hawaii celebrating our wedding anniversary and decided to do this experience. Our pilot Patch was amazing and very knowledgeable about the sites that we got to see. Hands down when we are back in Hawaii we would definitely do this experience again.” Tara_M, January 2025

What?: Surfing has long been a favorite pastime in Hawaii and Oahu is a great place for beginners to try riding a wave for the first time during a surf lesson. While there are great surfing conditions around the island, Waikiki’s beaches are a particular favorite for anyone dipping their toes into the sport.

When?: Surfing conditions are best in the morning when the waves are smoother and a little more predictable.

What one reviewer said: “We had a great time learning to surf. Keith was so awesome and patient with us. He helped tremendously and my daughter was surfing in no time.” Anissa_L, February 2025

What?: One of the best things to do on Oahu is enjoy the beauty of the ocean. With a guided scuba diving tour you can head down to see the island’s marine life, including fish, coral, turtles, eels, and more.

When?: Do not scuba dive within 24 hours of flying or ziplining, as the change in altitude can give you decompression sickness.

What one reviewer said: “Incredible! We were first time divers and I was nervous but the instructors were so patient and kind! We found sea turtles almost right away and saw a lot of colorful fish. Wonderful time!” Chris_S, May 2024
