The best things to do in Honolulu fit together better than you might expect. In a few days you can watch sunrise from the rim of Diamond Head, spend a quiet morning at Pearl Harbor, snorkel Hanauma Bay, and close the day with a luau. Honolulu is Hawaii’s capital and the main hub of Oahu, mixing world-famous beaches, the only official royal palace in the United States, moving World War II memorials, volcanic hikes, and a rich food scene. This 2026 guide covers the top sights, the prices and reservation rules you need to know, and how to get around.
Key Highlights
- Book ahead for the big three: Diamond Head, Hanauma Bay, and the USS Arizona Memorial program all run on timed reservation systems that sell out.
- Pearl Harbor’s visitor center and the USS Arizona Memorial program are free, with a $1 reservation fee per ticket through recreation.gov. Plan on a half day.
- Diamond Head costs $5 per person plus $10 per vehicle for non-residents; reserve up to 30 days ahead on the state’s park portal.
- Waikiki, downtown, and most sights are easy without a car: TheBus caps at $7.50 per day on the HOLO card.
- Three to four days cover the essentials; add two more days for the North Shore and the Windward side.
Getting to Honolulu and Getting Around
Most visitors arrive at Daniel K. Inouye International Airport (HNL), about 6 miles west of downtown Honolulu and roughly 9 miles from Waikiki. Taxis, rideshares, hotel shuttles, and rental cars serve the terminals. Waikiki itself is compact and walkable. TheBus is the island-wide public option: as of July 2026 the adult cash fare is $3.25 per boarding with no transfers, so a reloadable HOLO card is the better deal, with a $3 two-hour pass and fares capped at $7.50 per day (per the City and County of Honolulu). The Waikiki Trolley runs sightseeing lines between Waikiki, Diamond Head, Ala Moana, and downtown. Rental cars give the most freedom for day trips, but Waikiki resort parking fees are steep.
Best Time to Visit Honolulu
Honolulu is a year-round destination with daytime highs generally between 75 and 88 degrees. Hawaii has two seasons: the warmer, drier kau season (roughly May through October) and the cooler, wetter hooilo season (roughly November through March). The south shore stays calm and sunny in winter while the North Shore picks up its famous big surf, and humpback whales pass through roughly December through April. Crowds and prices peak around the winter holidays and in summer, so April, May, September, and October often offer the best balance.
What to Expect: The Best Things to Do in Honolulu
Waikiki Beach
Waikiki is where most Honolulu trips begin. The roughly two-mile beach along Kalakaua Avenue is famous for gentle, rolling waves that make it one of the best places in the world to learn to surf, and surf schools line the sand with beginner lessons. The Duke Kahanamoku statue at Kuhio Beach is the classic photo stop, and the beachfront promenade is made for sunset strolls. Behind the sand, Kalakaua Avenue is packed with shops and restaurants. On Friday evenings, fireworks are usually launched off Waikiki, though the schedule can change.
Hike Diamond Head (Leahi)
Diamond Head is Honolulu’s most recognizable landmark, a volcanic tuff crater formed about 300,000 years ago, and the summit trail is the island’s signature hike. The trail runs 0.8 miles each way with 560 feet of elevation gain, passing through a 225-foot lighted tunnel and up steep stairs to a former military fire control station with sweeping views from Koko Head to Waianae. Allow 90 minutes to two hours, bring water, and go early to beat the heat. Since May 2022, non-residents need advance reservations booked up to 30 days ahead on gostateparks.hawaii.gov: entry is $5 per person and parking is $10 per vehicle (per the Hawaii Division of State Parks). Open 6 a.m. to 6 p.m. daily, closed Christmas Day and New Year’s Day. Our Diamond Head hiking guide walks through the reservation steps.
Pearl Harbor and the USS Arizona Memorial
Pearl Harbor is about 10 miles west of Waikiki and deserves at least half a day. The Pearl Harbor National Memorial visitor center is open 7 a.m. to 5 p.m. daily, with free museums covering the road to war and the December 7, 1941 attack. The centerpiece is the 45-minute USS Arizona Memorial program: a short film followed by a Navy shuttle boat to the memorial over the sunken battleship, where 1,102 of the 1,177 sailors and Marines killed aboard the Arizona remain entombed. The program is free, but you need a timed ticket through recreation.gov (a $1 per-ticket service fee), and same-day tickets are limited, so book early. Parking costs $7, and large bags are not allowed past security; paid storage is available nearby. The Battleship Missouri, the Pearl Harbor Aviation Museum, and the submarine museum on Ford Island are partner-run with separate paid tickets, reachable by shuttle. See our USS Arizona Memorial visitor guide for the full rundown.
Iolani Palace and Downtown Honolulu
Downtown holds one of the city’s most underrated sights: Iolani Palace, completed in 1882 and the only official royal residence on American soil. Home to Hawaii’s last monarchs, King Kalakaua and Queen Liliuokalani, its restored throne room, grand hall, and private suites tell the story of the Hawaiian Kingdom. Tours run Tuesday through Saturday, 9 a.m. to 4 p.m., closed Sundays, Mondays, and holidays. Adult admission runs about $28 for a self-guided audio tour and $34 for a docent-led tour, with discounts for teens, children, military, and Hawaii residents; book ahead at iolanipalace.org since docent tours sell out. Nearby are the King Kamehameha statue and the National Memorial Cemetery of the Pacific at Punchbowl, set in an extinct crater with panoramic city views.
Museums: Bishop Museum, Waikiki Aquarium, and the Honolulu Zoo
The Bishop Museum holds the world’s premier collection of Hawaiian and Pacific artifacts, from feather work and royal heirlooms to a planetarium and a science adventure center that kids love. General admission uses dynamic pricing and typically runs in the mid-$30s for adults, with reduced rates for youth, seniors, kamaaina, and military; children under 4 are free. Our Bishop Museum guide covers what to see first. On the Diamond Head end of Waikiki, the Waikiki Aquarium sits on the shoreline at 2777 Kalakaua Avenue. Founded in 1904, it focuses on Hawaiian and Pacific marine life; general admission is $12 (per waikikiaquarium.org), open 9 a.m. to 4:30 p.m. daily. Across the street, the Honolulu Zoo and Kapiolani Park make an easy half-day for families.
The Honolulu Food Scene
Honolulu’s food is a highlight in its own right. Start with the classics: a poke bowl from a neighborhood seafood counter, a plate lunch with mac salad, shave ice on a hot afternoon, and warm malasadas (Portuguese fried doughnuts) from Leonard’s Bakery, a local institution. The KCC Farmers Market at Kapiolani Community College on Saturday mornings is the island’s best-known market. Chinatown’s markets, lei shops, and restaurants are worth a dedicated wander. Tipping follows mainland US norms: 15 to 20 percent at restaurants.
Snorkeling at Hanauma Bay
About 10 miles east of Waikiki, Hanauma Bay is a flooded volcanic crater turned marine life conservation district, and the easiest great snorkeling on Oahu. The calm, shallow water holds hundreds of species of tropical fish, and all visitors watch a short orientation video about reef protection before entering. Non-resident admission is $25, and reservations are required through the City and County of Honolulu’s system, released two days ahead at 7 a.m. Hawaii time; weekend slots go fast. The bay is open Wednesday through Sunday, 6:45 a.m. to 4 p.m., closed Monday and Tuesday. Bring reef-safe sunscreen and never touch the coral. Our Hanauma Bay snorkeling guide explains the booking window, and our Honolulu snorkeling roundup lists alternatives.
Luaus and Evening Entertainment
A luau is the classic Honolulu evening: hula and fire-knife dancing, live Hawaiian music, and a feast built around kalua pig cooked in an underground imu oven, plus poke, poi, and tropical desserts. Well-known options include Paradise Cove in Ko Olina and Germaine’s Luau on the west side; most run four to five hours with Waikiki hotel pickup. Expect roughly $100 to $200 or more per person depending on the package, and book several days ahead in peak season. For a free evening, the hula performances at the Kuhio Beach Hula Mound run on select evenings.
Hiking, Lookouts, and Waterfalls
Beyond Diamond Head, Honolulu has hikes for every level. The Manoa Falls trail is an easy rainforest walk of about a mile and a half round trip ending at a waterfall. For views with almost no effort, drive to the Tantalus Lookout at Puu Ualakaa State Wayside near golden hour, or stop at the Nuuanu Pali Lookout, a dramatic and famously windy clifftop over the Windward coast. Serious hikers tackle the Koko Crater stairs, more than a thousand railroad-tie steps with a sweeping panorama as the payoff. Trails can be muddy after rain, so wear shoes with grip.
Day Trips: the North Shore and Windward Oahu
With a car or a guided tour, the rest of Oahu opens up. The North Shore, about 45 minutes from Waikiki, is legendary for winter surf at Banzai Pipeline and Sunset Beach, plus garlic shrimp trucks, shave ice stands, and summer snorkeling at Sharks Cove. Waimea Valley pairs a botanical garden walk with a waterfall swim when lifeguards permit. On the Windward side, Lanikai and Kailua are often called the island’s prettiest beaches, and the Halona Blowhole and Makapuu Point are easy stops on the scenic southeast drive. If you would rather not drive, circle island tours bundle the highlights into one long day.

Practical Tips for Visiting Honolulu
- Reserve early. Diamond Head, Hanauma Bay, Iolani Palace, and the USS Arizona Memorial all require advance booking.
- Pack reef-safe sunscreen. Hawaii bans sunscreens with oxybenzone and octinoxate.
- Respect the ocean. Never turn your back on the surf, check advisories before swimming, and keep your distance from sea turtles and monk seals; touching them is illegal.
- Hydrate on hikes. Diamond Head and Koko Crater are fully exposed. Carry more water than you think you need and start before 9 a.m.
- Mix free and paid days. Beaches, lookouts, the palace grounds, and the Pearl Harbor museums cost nothing and balance out pricier days.
Frequently Asked Questions
How many days do you need in Honolulu?
Three to four days cover the essentials: Waikiki, Diamond Head, Pearl Harbor, and either Hanauma Bay or a museum day. Five to seven days add the North Shore, the Windward side, and a luau evening.
Is Honolulu expensive?
It is one of the pricier US beach destinations, but manageable with planning. Beaches, lookouts, and the Pearl Harbor museums are free. Plate lunches, food trucks, and TheBus day passes capped at $7.50 keep costs down, while Iolani Palace ($28-$34), Bishop Museum (mid-$30s), and luaus ($100-$200+) are the biggest costs after lodging.
Do I need a car in Honolulu?
Not necessarily. From Waikiki you can reach the beach, Diamond Head, downtown, and Ala Moana on foot, by TheBus, or on the Waikiki Trolley, and TheBus also serves Pearl Harbor and Hanauma Bay. A rental car pays off for North Shore and Windward day trips, where bus travel is slow.
Is Pearl Harbor free, and do I need reservations?
Yes. The visitor center and its two museums are free, and the USS Arizona Memorial program is free too. You need a timed program ticket through recreation.gov ($1 per-ticket fee); walk-up tickets are very limited, so book early. Parking is $7; the Missouri, Aviation Museum, and submarine museum charge separate admission.
What is the best free thing to do in Honolulu?
Waikiki Beach itself is the classic answer. Other top free picks: the Nuuanu Pali Lookout, the Manoa Falls trail, the Iolani Palace grounds, the Punchbowl cemetery, the hula shows at Kuhio Beach, and the Pearl Harbor museums.
Is Honolulu good for families with kids?
Yes. Waikiki’s gentle surf suits young swimmers, and kids love the Waikiki Aquarium, the Honolulu Zoo, the Bishop Museum’s science center, and Hanauma Bay snorkeling. Many luaus offer reduced child rates.
