Honolulu

Honolulu, Hawaii, is the city on Oʻahu with the state's largest airport, Daniel K. Inouye International, and a practical base for Waikīkī, Pearl Harbor, Diamond Head and Hanauma Bay. Pearl Harbor National Memorial counted 1,534,226 recreation visits in 2025.

Most things to do in Honolulu on a first visit have a booking rule or a fixed window, so the order of your days matters more than the distances. We read the figures below on 3 November 2026 on the pages of the National Park Service, the state parks division, the City and County of Honolulu, ʻIolani Palace, the state airports and the Department of Taxation, and in NOAA's normals.

We could not read Bishop Museum's hours or prices, the airport's taxi rates, whether contactless cards pay on transit, or inter-island flight times and fares, so this page gives none of them.

Which things to do in Honolulu must be booked ahead, and when do tickets open?

Pearl Harbor's USS Arizona Memorial, Diamond Head and Hanauma Bay all need booking ahead, each on its own release rule, and ʻIolani Palace sells online only.

Monday leaves only Pearl Harbor and Diamond Head, because Hanauma Bay and ʻIolani Palace are closed. Tuesday adds the palace and Sunday adds the bay, and all four are open from Wednesday to Saturday.

Honolulu's release times are in Hawaii time, so convert them before you set an alarm. Hawaii keeps UTC−10 all year, with no daylight saving. Honolulu is 2 hours behind Los Angeles and 5 behind New York from 1 November 2026 to 14 March 2027. While the mainland is on daylight saving, the gap is 3 and 6 hours.

No official source gives a number of days for Honolulu. A ranger tip on the Park Service's Arizona page says only "Plan to spend at least 2-8 days on Oahu." The visits themselves are short: 45 minutes for the Arizona programme after an hour's early arrival, one to two hours for Diamond Head, and 60 to 90 minutes for the palace.

How do USS Arizona Memorial tickets and bag rules work at Pearl Harbor?

USS Arizona Memorial tickets are free but available only on Recreation.gov, at a non-refundable $1 fee per ticket. They are released daily at 3 p.m. Hawaii time in two windows, 8 weeks and 24 hours ahead, with a limit of 10 tickets a day. Everyone in the party needs one, infants over 1 included. In-person tickets on the day have been discontinued. A free standby callback exists, but it can take several hours and may not run at peak times.

Pearl Harbor National Memorial charges no entrance fee and is not on the 2026 list of parks with a $100 non-resident surcharge. Our guide to national park fees for international visitors names the eleven that are. Parking costs $7 a day, paid on the day by QR code and never in advance. Parking is free on Veterans Day, 11 November 2026. Recreation.gov calls this a high-theft area, so leave no valuables in the car.

Arrive at least an hour before your ticket, and check in 10 minutes before it. Boats leave every 15 minutes from 8 a.m. to noon and from 1 to 3:30 p.m., and neither they nor the memorial have restrooms. The visitor centre opens daily from 7 a.m. to 5 p.m., except Thanksgiving, Christmas and New Year's Day.

The Park Service's pages word the bag rule differently, and only the safety page gives dimensions: a wallet or clutch up to 1.25 × 2.25 × 5.5 inches, or a clear plastic bag. The Pacific Fleet Submarine Museum stores other bags for a fee.

The Park Service calls the drive from Waikīkī about 45 minutes, for about 12 miles on our own routing. Take H-1 exit 15A, "Arizona Mem./Stadium", and avoid the "Hickam AFB/Pearl Harbor" exit. By rail, leave Skyline at Hālawa Aloha Stadium Station, cross Kamehameha Highway to the ocean side and walk east. TheBus 40, 42 or 51 also covers that one stop.

The submarine museum, the Pearl Harbor Aviation Museum and the Battleship Missouri Memorial are separate sites with their own admission. We did not read their prices.

What does Diamond Head ask of a non-resident before the hike?

Diamond Head State Monument requires non-residents to reserve entry and parking, up to 30 days ahead, and anyone without a reservation is turned away. Entry costs $5 a person, free at 3 and under, and a vehicle $10, by credit card only.

The monument is open from 6 a.m. to 6 p.m. daily, except Christmas and New Year's Day. The last reservation is at 4 p.m., the last entry at 4:30 p.m., and the gates lock at 6 p.m. Arrive within the first 30 minutes of your slot. Parking is very limited, and a parking reservation must leave by its end time.

Refunds run up to 3 days before the visit, and a $5 cancellation fee and service fees may apply. No-shows, late arrivals and rain get nothing back. The state parks notice read on 3 November 2026 named no closure at Diamond Head.

The trail, built in 1908, climbs 560 feet in 0.8 mile, and its last tenth of a mile is stairs. The two official hike times differ: the park page says allow 1.5 to 2 hours, and the reservation FAQ says 60 to 90 minutes.

How do you get into Hanauma Bay on a two-day booking window?

Hanauma Bay Nature Preserve releases bookings only two days before the visit, from 7 a.m. Hawaii time: Monday for Wednesday, through Friday for Sunday. Each reservation holds up to 5 adults and 5 children. A non-resident pays $25 plus a 2.35% online fee, by Visa, Mastercard or JCB, and children 12 and under are free. Reservations are non-refundable unless the bay is closed.

The City and County of Honolulu closes the preserve every Monday and Tuesday, and on Christmas Day and New Year's Day. Entry runs from 6:45 a.m. to 1:30 p.m., the beach clears at 3:30 p.m. and everyone is out by 4 p.m. The city adds that this can change at any time. The state's lifeguard list prints "Sun-Mon" for the bay, but the city runs the preserve, so plan on the city's days.

Walk-in entry exists but is not guaranteed: the city says about a quarter of access is for walk-in or drive-in visitors. Tickets are issued daily from 6:45 a.m. at the parking-lot gate, with your whole group present. A reservation does not include a parking stall, and parking costs non-residents $3, in cash at the booth.

Every visitor watches an educational video first. City buses no longer run into the bay, but Route 22 stops at the top, on Kalanianaʻole Highway. The city calls snorkelling one of the most dangerous activities visitors take part in, and warns of sharp coral near the shore.

Which ʻIolani Palace tour should you book, and what can you wear?

ʻIolani Palace sells a docent-led tour at $34 and a self-led audio tour at $28 for an adult, and beachwear is not allowed on either. Tickets are online only, with no walk-ups or same-day reservations, and children aged 4 and under are free.

The palace is open from 9 a.m. to 4 p.m., Tuesday to Saturday. It also closes on 26 November, 30 November and 25 December 2026. Its own pages disagree on which day each tour runs, so check the day on the booking page.

Shirts and footwear are required, and bathing suits and beach cover-ups count as inappropriate. Large bags, backpacks, luggage, food and drink stay out. Parking on the grounds costs $4 for two hours.

What is there in Waikīkī besides the beach?

Waikīkī also has Kapiʻolani Regional Park and the Waikīkī Aquarium, beyond its four lifeguarded beaches. The city's park covers 200 acres, was dedicated in 1877 and may not charge an entrance fee.

Waikīkī Aquarium, at 2777 Kalākaua Avenue, charges $12 for general admission and $5 for ages 4 to 12 or seniors aged 65 and over. Ages 3 and under are free. The aquarium opens daily from 9 a.m. to 4:30 p.m. and says it stays open during its renovations. It closes on Honolulu Marathon Day, 13 December 2026, and on Christmas Day.

Waikīkī is the simplest area to stay in without a car. The W Line runs from the airport every 10 minutes, Diamond Head's trailhead is about 2.5 miles away and ʻIolani Palace about 4. We name no hotels and no room prices, because we read none.

How do you reach Waikīkī from Honolulu's airport when Skyline stops at Kalihi?

TheBus W Line is the way from Honolulu's airport to Waikīkī, because Skyline rail stops at Kalihi and does not reach Downtown, Ala Moana or Waikīkī. The city calls the W Line, every 10 minutes, the most affordable trip between the two. After Skyline closes at 10:30 p.m., Route 42 replaces the W Line. The A Line goes Downtown, and the W Line also runs from Āhua Lagoon Drive station.

Skyline runs 13 stations, from Kualakaʻi in East Kapolei to Kahauiki at Kalihi Transit Center. Lelepaua Station sits on the inland (mauka) side of Terminal 2, with a walkway to the Terminal 2 and International garages.

Trains run from 4 a.m. to 10:30 p.m. every day, every 10 minutes until 8:30 p.m. and every 15 minutes after that. The stations to Civic Center are under construction, with a March 2031 readiness date, and Kakaʻako and Ala Moana are a separate phase after them.

TheBus and Skyline share one fare table. TheBus's own site timed out when we checked, so these figures come from the city's Department of Transportation Services.

Fare capping means that once a HOLO card reaches the cap, the rest of the day or month is free. One child aged 5 or under rides free with a paying rider, without taking a seat. HOLO cards are sold at Lelepaua's vending machines. On Skyline, luggage goes in the overhead area or on your lap.

Taxis wait on the centre median in front of baggage claim, with dispatchers in yellow shirts. Rideshare pick-up is on the ground level: the Terminal 1 kerb by Baggage Claim 6, and the Terminal 2 medians across from Baggage Claims 19/20 and 31.

The airport's home page lists non-stop cities such as Haneda, Narita, Seoul, Sydney and Vancouver, as examples rather than a timetable.

How far is the North Shore from Waikīkī, and what needs a flight?

The North Shore is about 35 to 43 miles from Waikīkī on our own routing, and our sources give no bus route there, so plan it as a drive. We found no official figure for these trips, and our routing can run up to about 9% off on a long route. Our guide to renting a car in the USA covers the paperwork.

Hawaiʻi Volcanoes National Park and Haleakalā National Park are on other islands, so each needs a flight from Honolulu. The airport names flights to Kahului on Maui, and to Kona and Hilo. Our guide to Hawaii compares the islands.

What gets added to a Honolulu hotel bill?

A Honolulu hotel bill carries 11% state transient accommodations tax and 3% county tax, and the general excise tax can be passed on at up to 4.712%. By our own arithmetic, that adds at most 18.712%. A real bill can differ by cents, because a hotel may exclude excise tax it visibly passes on from its accommodations tax base.

Hawaii has no sales tax. The general excise tax falls on the business and forms part of the price, so a $100 price can come to $104.71 at the till. Our guide to sales tax in the USA sets Hawaii beside the other states.

How little rain does Honolulu's airport get, and when does it fall?

Honolulu's airport gets 16.41 inches of rain a year on NOAA's 1991 to 2020 normals. March is the wettest month, at 2.36 inches, and June the driest, at 0.50. The high moves only from 81°F in January to 89°F in August, and 31.6 days a year reach 90°F.

Hurricane season runs from 1 June to 30 November. Pearl Harbor closed for weather on 16 August 2026, so check its alerts before a summer visit.

When do box jellyfish and high surf reach Honolulu's beaches?

Box jellyfish regularly swarm to Hawaii's south and leeward shores 9 to 10 days after the full moon, says the State Department of Health. Waikīkī is on the south shore, though the page names no beach. The page links Waikīkī Aquarium's calendars through 2030.

Winter surf runs from November to April, with extremely high waves at many north and west shore beaches. Waimea Bay is calm in summer and pounded in winter. From May to October, large swells can arrive often on south shores, which is where Waikīkī lies.

Lifeguards staff Duke's, Kūhiō, Queen's and Kapiʻolani Park beaches in Waikīkī, plus Ala Moana and Magic Island, every day from 8 a.m. to 6:30 p.m. The state's page says to call 911 for lifeguard services if a tower is empty. HawaiiBeachSafety.com updates conditions at lifeguarded beaches every 15 minutes, and the city's HNL.info app pushes alerts and tower closures.

The city warns visitors off wet rocks, and off jumping from the Kapahulu wall or Waimea Bay rock. The state adds that a missing warning sign does not mean there is no threat.
