Things to Do in Honolulu

Honolulu is the rare beach city where the most important planning happens before you leave home. Three of the four things you probably came for - the USS Arizona Memorial, Diamond Head and Hanauma Bay - all sit behind reservation systems with short booking windows, and turning up on the day mostly doesn’t work any more. Sort those out first, then treat Waikiki as your base and Oahu as the day-trip menu.

Count backwards from your arrival date and the calendar looks like this. Arizona Memorial tickets open 56 days ahead at 3 p.m. Hawaii time and can be gone in minutes. Hanauma Bay opens exactly two days ahead at 7 a.m. Diamond Head takes non-resident bookings through the state parks system. Set three alarms, and understand that a missed window costs you the whole activity rather than a wait in line.

Pearl Harbor: free, but not walk-up

The park itself costs nothing, and neither does the boat program out to the USS Arizona Memorial. What you pay is a $1 non-refundable Recreation.gov service fee per ticket, plus $7 a day to park. Tickets drop on a rolling 56-day window at 3 p.m. HST, with a smaller batch of next-day tickets at the same hour the afternoon before. The Park Service stopped handing out free same-day tickets at the visitor center, so an unreserved arrival means the standby line or nothing.

One rule stops a lot of visitors at the gate. Pearl Harbor has a strict bag policy: anything that offers concealment and is bigger than about 1.25 by 2.25 by 5.5 inches has to stay outside. Clear bags and small clutches get through; backpacks, camera bags and purses do not. There’s paid storage near the entrance run by the submarine museum, but the simpler answer is to leave everything in the car. Allow three hours for the memorial and the museums, more if you’re adding the Missouri or the Bowfin, which are separately ticketed and run by different operators.

Diamond Head and Hanauma Bay, in the right order

Diamond Head is the crater behind Waikiki and the easiest big walk on the island: about 45 minutes up a paved-then-stepped trail inside an extinct tuff cone, ending at a World War I fire control station with the whole south shore below. Non-residents need reservations for both entry and parking through the state parks site, at $5 a head plus $10 a vehicle, and Hawaii residents go free with a state ID. Gates run 6 a.m. to 6 p.m. with last entry at 4:30. Book the earliest slot you can stand: by nine the stairs are hot and full.

Hanauma Bay is the snorkeling bay east of town, and it is now run more like a nature reserve than a beach. It is closed Mondays and Tuesdays. Entry runs 6:45 a.m. to 1:30 p.m. and everyone is out by 4. Non-residents aged 13 and up pay $25 plus a small online fee; residents, children under 13 and active US military are free; parking costs $3 and the lot is small. Reservations open at 7 a.m. Hawaii time exactly two days before your date and go quickly. Every visitor, every visit, watches a short conservation video before walking down to the water - there’s no skipping it, and the ban on standing on coral is enforced.

Waikiki, and what it is good at

Waikiki gets a lot of scorn and most of it is unfair. Yes, it’s two miles of hotels on reclaimed swamp behind a groomed beach. It is also the one part of Hawaii where you can eat, drink, swim, rent a board and get a bus without a car, and the surf break offshore is the gentlest beginner wave in the state - which is why surfing instruction was invented here. Take a lesson at Canoes or Queens, then walk to Kaimana Beach at the Diamond Head end, which is where people from Honolulu swim.

The Hawaii that is not a beach

Iolani Palace, twenty minutes west in the civic center, is the only royal palace on American soil, built for King Kalakaua in 1882 and wired for electric light in 1886, before the White House had it. It is also where Queen Liliuokalani was imprisoned after the 1893 overthrow of the Hawaiian Kingdom, and the tour doesn’t soften that. An hour here reframes the rest of your trip.

Chinatown, a few blocks further, is the best eating in the city and the least polished: century-old markets, lei stands, Vietnamese pho counters, and a night scene of bars in old storefronts along Hotel and Nuuanu. Go hungry, go in daylight for the markets, and come back after dark for the bars.

For a short, green, non-committal hike, Manoa Falls sits fifteen minutes inland in a rainforest valley: about 1.6 miles round trip on a muddy track to a thin waterfall. Wear shoes you don’t mind ruining.

Eat like a local, not like a resort

Local food here has nothing to do with luau menus. Poke, cubed raw fish with shoyu, sesame and onion, is sold by the pound at supermarket and corner-store counters, and the good stuff comes from places with a line of tradesmen out the door at midday, not from restaurants. The plate lunch - two scoops rice, macaroni salad and something grilled or fried - is the workingman’s meal that came out of plantation camps. And malasadas, Portuguese doughnuts without a hole, are a Honolulu obsession worth building a morning around.

Day trips around Oahu

The island is small enough to loop in a day, and two directions are worth it. Head north for the North Shore: Haleiwa’s old plantation-town main street, shave ice with sweet beans and condensed milk, sea turtles hauled out at Laniakea, and the winter surf at Waimea, Sunset and Pipeline, where the waves stop being a photo opportunity and turn dangerous. In summer the same beaches are flat and swimmable.

Head east and the windward coast opens up: the Nuuanu Pali Lookout, where the wind comes over the ridge hard enough to lean on and Kamehameha won Oahu in 1795, then Kailua and Lanikai beaches, and the green ridges of Kualoa that stand in for prehistory in half of Hollywood’s dinosaur films.

Where to sleep, and which month to pick

Waikiki holds almost all the hotel stock, and the price gap inside it is bigger than the map suggests. Rooms on the Diamond Head end, around Kapahulu and Kaimana, are quieter, cheaper and closer to the beach locals use; the middle of Kalakaua Avenue is where the resorts and the shopping are; the Ala Moana end puts you next to the biggest mall in the state and a decent beach park with calm water. Kailua on the windward side is the alternative for anyone who wants a residential neighborhood and a much better beach, at the cost of a 30-minute drive over the pali to everything else.

Season matters less here than on the mainland, because Honolulu sits at about 80F all year. What changes is rain, surf and price. Mid-December to early January is the most expensive two-week stretch of the year, and the north-shore waves are at their most spectacular and most lethal. February to April brings the last of the whales and the last of the winter rain. Summer means calm water on every coast and school-holiday crowds. If you want the best combination of cheap flights, warm sea and thin crowds, aim for late April to early June or the second half of September.

Getting around, and the rail question

Honolulu opened the second segment of its Skyline rail in October 2025, which now runs from Kapolei in the west through Pearl Harbor and the airport to the Kalihi Transit Center. It is fast, elevated and useful for exactly one visitor trip: the airport. It doesn’t yet reach downtown or Waikiki, so anyone telling you the train will replace a car hasn’t looked at a map. Fares work on a HOLO card, sold at vending machines in every Skyline station and at ABC Stores in Waikiki, with 1-, 3- and 7-day unlimited passes that also cover TheBus.

If you’re staying in Waikiki and doing one or two day trips, rent a car for those days only and skip the $40-plus nightly hotel parking the rest of the week. Between November and April, keep an eye on the water on the drive east and north: humpbacks are in these channels all winter, and the legal minimum distance is 100 yards for a reason.
