Things to Do in Honolulu and Waikiki
Most visitors stay in Waikiki, on Oahu’s south shore. Many of the best things to do in Oahu are close by, so this is the perfect place to start.
1. Spend a Day on Waikiki Beach
Waikiki Beach is the most famous beach in Hawaii. The water is usually calm, and the beach is lined with hotels, cafes and shops. Rent a board, take a canoe ride or simply swim. Then walk Kalakaua Avenue for food and shopping. Visit the Duke Kahanamoku statue to honor the father of modern surfing.
2. Take a Surf Lesson
Waikiki is one of the best places in the world to learn to surf. The waves here are small and gentle on most days. Many surf schools give lessons right on the beach. A private lesson is a good choice if you are nervous. Many beginners stand up during their very first lesson.
3. Hike Diamond Head
Diamond Head is the volcanic crater you see behind Waikiki. The hike to the top is about 1.6 miles round trip with roughly 560 feet of climbing. Plan about 1.5 to 2 hours. The views over Waikiki and the ocean are worth it.
Out-of-state visitors must book ahead on the official Diamond Head reservation site. Entry is $5 per person, and parking is $10 per car. You can book up to 30 days in advance. Go early, because there is little shade on the trail.
4. Watch the Friday Night Fireworks
Every Friday night, the Hilton Hawaiian Village puts on a free fireworks show over the ocean. It usually starts around 7:45 or 8:00 p.m. and lasts only a few minutes. Watch from the beach near the hotel or from Fort DeRussy Beach. Times can change, so check with the hotel before you go.
5. Go on a Sunset Sail
A sunset catamaran sail is one of the most relaxing things to do in Oahu. Many boats leave right from Waikiki Beach. Most trips last about 90 minutes to two hours. Some include drinks. Friday sails often time their return with the fireworks.
6. Visit Iolani Palace
Iolani Palace was home to Hawaii’s last monarchs. It is often called the only royal palace in the United States. A guided or self-guided tour tells the story of the Hawaiian Kingdom. It sits in downtown Honolulu, a short drive from Waikiki.
7. Explore Chinatown and the Kaka’ako Murals
Honolulu’s Chinatown is full of small bakeries, lei shops, bars and cafes. Next door, the Kaka’ako area is famous for large street murals. You can walk past colorful walls all year. Several local breweries are close by, too.
8. Learn Hawaiian History at Bishop Museum
Bishop Museum is the best place on the island to learn about Hawaiian and Pacific culture. It has royal objects, ancient tools and a planetarium. Plan at least two hours. It is a great choice on a rainy day.
Visit Pearl Harbor National Memorial
9. See the USS Arizona Memorial
Pearl Harbor is one of the most moving places to visit in Oahu. The memorial floats above the sunken USS Arizona. Entry to the park is free.
The USS Arizona Memorial program needs a timed ticket from Recreation.gov. Each ticket has a $1 booking fee. Tickets open 8 weeks ahead at 3 p.m. Hawaii time. More tickets are released the day before. The visitor center is open daily from 7 a.m. to 5 p.m. Parking costs $7 per day.
The Battleship Missouri and the Pearl Harbor Aviation Museum are nearby. They need separate paid tickets.
Things to Do on Oahu’s East Side
The east, or windward, side has Oahu’s best beaches and green cliffs. For many travelers, this side holds the most beautiful things to do in Oahu. It also makes a perfect day trip from Waikiki.
10. Snorkel at Hanauma Bay
Hanauma Bay is a protected bay inside an old volcanic crater. Its calm water is home to colorful fish and, sometimes, sea turtles. It is one of the most popular things to do in Oahu, so plan ahead.
Here are the key rules for 2026:
- Hanauma Bay is open Wednesday to Sunday. It is closed Monday and Tuesday.
- Entry is from 6:45 a.m. to 1:30 p.m. Everyone must leave by 4 p.m.
- Visitors 13 and older pay $25. Kids 12 and under enter free.
- Parking costs $3 and fills up early.
- Reservations open two days ahead at 7 a.m. Hawaii time and sell out fast.
- Everyone watches a short conservation video before going down to the beach.
Book on the Honolulu Parks and Recreation website. Bring reef-safe sunscreen. Hawaii bans sunscreens with oxybenzone and octinoxate because they harm coral.
11. Walk the Makapu’u Point Lighthouse Trail
This paved trail is easy, even with a stroller. It is about 2 miles round trip. You get wide ocean views and a red-roofed lighthouse below. In winter, you may spot whales from the top. Start early, because there is no shade.
12. Stop at Halona Blowhole
Halona Blowhole is a quick stop on the drive from Hanauma Bay. Ocean water shoots up through a lava tube when waves hit. Stay behind the railings. The rocks and the small cove below can be very dangerous.
13. Relax on Lanikai Beach
Lanikai Beach has soft white sand and clear blue water. It often appears on lists of the best beaches in the world. The beach sits in a quiet neighborhood, and parking is very limited. Park at Kailua Beach Park and walk, or arrive early.
14. Hike the Lanikai Pillbox Trail
This short, steep trail climbs to old military bunkers called pillboxes. From the top, you see the twin Mokulua Islands. It is one of Oahu’s best sunrise hikes. Wear good shoes, as the path can be slippery.
15. Kayak to the Mokulua Islands
The Mokulua Islands, or “the Mokes,” sit just off Lanikai. You can paddle there by kayak from Kailua. Guided tours are best if you are new to kayaking. The islands are a protected seabird sanctuary, so follow all posted rules.
16. Tour Kualoa Ranch
Kualoa Ranch is a 4,000-acre private nature reserve on the windward coast. Its valleys appear in movies such as Jurassic Park. You can join a movie-site tour, ride a UTV, zipline or go horseback riding. Book your tour directly with the ranch.
17. Visit Ho’omaluhia Botanical Garden
This large garden sits below the tall, green Ko’olau Mountains. Entry is free. The famous road at the entrance is very photogenic, but stopping on it is not allowed. Park in the lots and walk instead. Check opening hours before you go.
Things to Do on Oahu’s North Shore
Some of the most unique things to do in Oahu are on the North Shore. In fact, it feels like a different island. It has small towns, food trucks and some of the biggest waves in the world. It is about an hour’s drive from Waikiki without traffic.
18. Drive the Kamehameha Highway
The coastal drive along Kamehameha Highway is a highlight of any trip. Take the windward coast north and stop at beaches, fruit stands and lookouts on the way. Then return through the middle of the island. Leave early, as you will want many stops.
19. Explore Haleiwa Town and the Shrimp Trucks
Haleiwa is the North Shore’s main town. It has surf shops, art galleries and colorful old buildings. Try a shave ice, then head to a shrimp truck for garlic shrimp. Popular trucks can have long lines, so go before noon.
20. Watch Big-Wave Surfing
From November to April, huge swells hit the North Shore. Famous spots like Banzai Pipeline and Waimea Bay draw the world’s best surfers. Watching from the sand is free. Do not swim when the surf is high.
From May to October, the North Shore is often much calmer. Then, beaches like Waimea Bay can be good for swimming and snorkeling. Always check the conditions at Hawaii Beach Safety before you get in.
21. See Sea Turtles
Green sea turtles often rest on North Shore beaches, such as Laniakea Beach. Watch them from a distance. NOAA recommends staying at least 10 feet away. Never touch or feed them, as they are protected by law.
22. Stop at the Dole Plantation
The Dole Plantation is on the way to or from the North Shore. It is a fun stop for families. Try the famous Dole Whip, walk the garden maze or ride the small train.
See a Luau at the Polynesian Cultural Center
23. Spend an Afternoon and Evening at the Polynesian Cultural Center
The Polynesian Cultural Center is in La’ie, on the northeast coast. It has island villages that share the cultures of Hawaii, Samoa, Tonga and other Pacific islands. Many visitors stay for a luau dinner and the evening show.
The center is usually open from noon to 9 p.m. It is closed on Sundays and most Wednesdays. Book luau tickets early, especially in summer and on holidays.
Things to Do on Oahu’s West Side
24. Swim in the Ko Olina Lagoons
Ko Olina is a resort area on the sunny west side. It has four calm, man-made lagoons that are great for kids and beginner snorkelers. The area is quieter than Waikiki. It is home to large resorts, including Disney’s Aulani.
Seasonal Things to Do in Oahu
25. Go Whale Watching
Humpback whales visit Hawaii from about November to May. Peak season is January to March. You can join a whale-watching boat from Honolulu. You can also watch from land at spots like Makapu’u Point.
More Things to Do in Oahu If You Have Extra Time
Staying longer? Add one or two of these extra things to do in Oahu.
- Manoa Falls Trail: a short rainforest walk near Honolulu that ends at a tall, thin waterfall. The path is often muddy, so wear shoes with grip.
- Koko Crater Railway Trail: a tough climb up more than 1,000 old railway steps. The view from the top is one of the best on the island.
- Waimea Valley: a botanical garden on the North Shore with a paved path to a waterfall. There is an entry fee.
- Foster Botanical Garden: a quiet garden in downtown Honolulu with huge old trees and rare plants.
What to Eat on Oahu
Eating is one of the most fun things to do in Oahu. Try these local favorites:
- Poke: fresh, seasoned raw fish. Even grocery stores sell good poke.
- Plate lunch: a meat dish with rice and macaroni salad.
- Shave ice: fine, fluffy ice with fruity syrups.
- Malasadas: Portuguese-style donuts, often filled with cream.
- Garlic shrimp: a North Shore food truck classic.
- Kalua pig and poi: traditional Hawaiian dishes, often served at a luau.
How Many Days Do You Need in Oahu?
Most first-time visitors need four to five days to see the island’s highlights. Here is a simple plan:
- Day 1: Waikiki Beach, a surf lesson and a sunset sail.
- Day 2: Diamond Head in the morning, then Pearl Harbor.
- Day 3: Hanauma Bay, Makapu’u and Lanikai Beach.
- Day 4: Kualoa Ranch and the North Shore.
- Day 5: Polynesian Cultural Center or a relaxed beach day.
With a week, you can slow down and add Ko Olina, Honolulu’s museums or a second day on the North Shore. Use our guide to creating the perfect travel itinerary to plan your days.
Do You Need a Car on Oahu?
You do not need a car for every day. Waikiki is walkable, and tours and buses reach many sights. However, a car makes the east side and North Shore much easier.
A good plan is to rent a car for only two or three days. Waikiki hotel parking can be expensive. Honolulu traffic is also heavy at rush hour, so leave extra time for the airport.
