Oahu is one of eight islands in the Hawaiian archipelago. It is home to some of the worldâs finest beaches, Hawaiiâs largest city Honolulu, and the majority of Hawaiian residents.
Oahu translates to âthe gathering place,â and the number of people on the island, combined with its breathtaking natural beauty, means there are near limitless activities for people of any age.
Before you head to Oahu, be sure to brush up on the local rules and regulations regarding tourists. Hawaii embraces sustainable tourism to maintain and protect the natural beauty, so they ask guests to leave no trace and support local nonprofit organizations that promote these initiatives.

19. Halona Blowhole Lookout
The Halona Blowhole Lookout is located near Hanauma Bay off Kalanianaole Highway and is worth a stop. Waters from the Pacific Ocean violently crash against the shore, and an old volcanic tube throws the sea waves high into the air.
Aside from the blowhole itself, the lookout offers spectacular views of the water and a great place to pull over and stretch your legs.

Skydiving isnât for everyone, but if youâre ready for the freefall, this activity is one of the best things to do in Oahu. A few different businesses offer skydiving along the island’s North Shore.
Starting from as high as 14,000 feet, most tours offer freefalls that last as long as 20 seconds. If youâre ready for the thrill of a lifetime, you can check out Pacific Skydiving or Skydive Hawaii to make a reservation.
25. Waimea Bay
The waves at Waimea Bay are not for the faint of heart. This bay is on the windward side of Oahu, and it shows. In winter (roughly November to April), the waves on this beach can be more than 20 feet tall.
The water at this beach is best traversed only by expert surfers and lifeguards. Waimea Bay is the place to be if you want to see expert surfers in action, not if youâre looking to ride your first wave.
In the summer, the waters of the bay calm, and this area becomes a popular spot to relax, snorkel, and dive.
26. Kaâena Point Trail
The Kaâena Point Trail is located in Kaâena Point State Park on the northwestern point of Oahu Island.
On hotter days, hikers should keep in mind that Kaâena Point Trail is a longer hike that doesnât offer much shade and has no drinking water available along the trail. Still, if youâre willing to make the 2.7-mile one-way trek, itâs worth it for what you will see along the way.

The campsites in the recreation area have showers, water fountains, and bathrooms available, though alcohol is not permitted anywhere in the park. You should come prepared for bugsâespecially mosquitos. However, itâs well worth it as camping in Hawaii is a truly memorable experience.
29. Wahiawa Freshwater State Recreation Area

Once you kayak the 30 minutes to the islands, you can hop out of your kayak, swim in the shallow waters, and explore the land. Whether renting a kayak and visiting the islands alone or following a guided tour, The Mokes are a must for anyone visiting Oahu.
31. Koko Crater Trail
The Koko Crater Trailâmore commonly called the Koko Head Stairsâis one of the most iconic hikes in Oahu. As Oahuâs most difficult hike with more than 1,000 stairs, this trail is best left to more experienced hikers and groups without small children.

33. The Manoa Falls Trail
The Manoa Falls Trail is a good choice for those with less experience to get some hiking in on Oahu. The trail has only a gentle slope and is a short 1.6 miles long. Itâs also just a 15-minute drive from Honoluluâperfect for families with restless children.
The size of the waterfall at the end of this trail may vary depending on the season and weather. Water from this waterfall depends on rainwater, so if you visit in the dry season, donât be surprised when the water is a smaller trickle.
Regardless of Manoa Falls waterfall, the trail will take you through a luscious green jungle under a gorgeous canopy of trees. This hike is absolutely worth the effort for the views along the way.
34. Hawaii State Art Museum
The Hawaii State Art Museum is the perfect activity for anyone that wants to learn more about the local culture while getting some time out of the sun. There’s always something new to see with an ever-changing array of exhibits that feature local artists.

Washington Palace, completed in 1847, is an important historical landmark in Oahu history. It originally housed Mary Dominis, who named it after George Washington with permission from King Kamehameha III.

At Washington Palace, you can walk amongst this history and learn about the life, career, and death of Queen Liliuokalaniâthe last monarch of the Hawaiian islands.
42. Honoluluâs Chinatown

43. Sea Life Park

Whether you go to the Sea Life Park for a dolphin encounter, a seal encounter, or just to get a closer look at the penguin habitat, make sure to pre-book your tickets and passes online, as they tend to sell out during peak seasons.
44. Segway tours
One of the best ways to get a full view of Honolulu (without being in a car) is to take a Segway tour. Many companies offer Segway tours around the city, and you can bring your entire family along.

45. Golfing
There are 40 golf courses on the Island of Oahu, and each offers a unique experience you wonât find anywhere else. There are options for every budget, from those who want a luxury PGA-golfing experience to those just looking to hit the course while they travel.

46. Kitesurfing
Kitesurfing, also called windsurfing, is a sport where you use a board and a small sail to glide across the water at high speeds. The best kitesurfing on Oahu is in Kailua Bay.
If you have never done this kind of surfing before, itâs best to start with an instructor who can help you learn how to navigate safely. Fortunately, Honolulu is home to plenty of kitesurfing schools that can help you get started.
Once you get going, kitesurfing can offer you the experience of a lifetime. From breathtaking views of the island from the water to the thrill of feeling like a low-flying, there is nothing like zipping across the water with only the wind to pull you along.
47. Biking
There are tons of bike trails around the island of Oahu. Whether youâre looking to experience some unique island mountain biking or you want to navigate the city’s streets, bike rental companies can get you started so you donât have to bring your bike from home.
48. Distillery tours
Whatever your alcohol preference, you will likely find an Oahu distillery to match it. Around the island, youâll find distilleries that produce rum, whiskey, scotch, and more. Because of the Japanese influence on the island, you can even visit a shochu (Japanese rice alcohol) or sake distillery.
49. Leonardâs Bakery
Leonardâs Bakery has been a staple of Oahu since 1952. It was opened by Leonard and Margaret DoRego, descendants of Portuguese immigrants. When they first opened the bakery, they stuck to traditional American desserts but quickly decided to include traditional Portuguese baked goods as well.
When the owners of Leonardâs included malasadas on the menu for the first time, they were reluctant. They werenât sure if the food would take off with white Americans or natives of the island, but it was a hit with both. To this day, Leonardâs Bakery represents the blend of cultures that makes Oahu and the surrounding islands unique.
Today, the bakery serves traditional Hawaiian baked goods like Pao Doce, Portuguese foods like malasadas, and traditional American desserts like pies and cupcakes.
50. Koko Crater Botanical Garden
The Koko Crater Botanical Garden is located on the eastern side of Oahu near Honolulu. It includes sixty acres of gorgeous gardens in the basin of the 200-acre Koko Crater.
The botanical garden includes plants from Hawaii, Africa, and Madagascar. There are tropical plants as well as plants native to arid climates.
