5 Days in Honolulu: First-Timer Itinerary
Five days is where Honolulu really opens up: Waikiki Beach and Diamond Head on Day 1, Pearl Harbor and the Bishop Museum on Day 2, Downtown and Iolani Palace on Day 3, a flex day on Day 4, and Hanauma Bay’s snorkeling finally added on Day 5. This is the first itinerary in the series where you actually get in the water instead of just admiring it from the sand. Shorter on time? Drop to 4 days . Have more? 6 and 7 days add even more breathing room.
Book these before you go
- Pearl Harbor / USS Arizona Memorial: free program, reserved ticket, book on recreation.gov up to 56 days ahead (3pm HST release, roughly $1 fee). Book this first, full stop.
- Diamond Head (Le’ahi): out-of-state visitors reserve a timed slot on gostateparks.hawaii.gov up to 30 days out, $5 a person plus $10 parking.
- Hanauma Bay: this itinerary actually uses it, so set an alarm. The reservation page opens exactly 2 days ahead at 7am HST, $25 a person plus $3 non-resident parking, and it’s closed Monday and Tuesday, so don’t plan your Day 5 for either.
Get a Waikiki hotel locked in early too, five nights in peak season books up fast: compare current rates on Booking.com .

Day 1: Waikiki Beach and Diamond Head
From the airport, TheBus routes 20/303 reach Waikiki for a $3 HOLO fare in 45 to 60 minutes, a shared shuttle runs $18 to $20 a person, and a taxi/rideshare runs $35 to $50. Waikiki Beach is crowded most days and still worth it, warm calm water, a lively promenade, and everything within a 20 to 30 minute walk.
Fit in the Diamond Head hike this afternoon or early the next morning if your slot allows: 0.8 miles one way, steep, 1.5 to 2 hours round trip, park open 6am to 6pm, last entry 4:30pm. Early beats the afternoon haze and the parking crunch. Kapiolani Park at Waikiki’s quieter eastern end is the reset button if the main beach gets to be too much.
Day 2: Pearl Harbor and the Bishop Museum
Arrive at Pearl Harbor’s visitor center a full hour before your reserved time, check in 10 minutes ahead, and expect a 45-minute program. Parking runs $7 a day via app or kiosk, separate from the free admission. For more depth than the standard program, browse guided harbor history tours on GetYourGuide .
The Bishop Museum takes the afternoon, general admission $34 to $39 with a small planetarium add-on, give it a real 2 to 3 hours. Poke by the pound ($15 to $22) or by the bowl ($12 to $18) makes an easy dinner after a full day of history.
Day 3: Downtown, Chinatown, and Iolani Palace
Iolani Palace opens the day, the only royal palace on US soil: self-guided audio tours run about $28, docent-led about $34, kids 4 and under free (schedules on the official site ). Chinatown is a five-minute walk for lunch, and the First Friday art walk (5 to 9pm, first Friday of the month) is worth timing your trip around if the dates line up.
Spend the afternoon at Ala Moana Center, one of the largest open-air malls in the US, or trade shopping for a swim at the calmer Ala Moana Regional Park beach next door.
Day 4: Flex day
Slow down deliberately here. Sleep in, swim at Ala Moana or back at Waikiki, and let lunch run long, Leonard’s Bakery malasadas ($1.75 to $2.50 plain, $2.25 to $4 filled) are worth the detour. Book a Hawaiian night for the evening instead of another restaurant: browse luau dates on Viator for live music, hula, and a full spread.
Day 5: Hanauma Bay snorkeling
This is the payoff day. Arrive right at opening (6:45am, last entry 1:30pm) since the reef and the parking lot both get busier as the morning goes on. Hawaii law requires reef-safe sunscreen (no oxybenzone or octinoxate) before you get in the water here or anywhere else in the state, so buy mineral sunscreen ahead of time if you didn’t pack it. Spend the rest of the day recovering on Waikiki Beach or shopping for anything you missed at Ala Moana.
Is 5 days enough to add Hanauma Bay?
Yes, and it’s the minimum that comfortably fits it without cutting anything else. Hanauma Bay’s booking window only opens 2 days out, so build in flexibility around your Day 5 date in case the exact slot you want isn’t available yet when you check.
What’s the best day to fit the reef snorkel?
Later in the trip works better than earlier, since the booking window only opens 2 days ahead and you’ll know your other days are locked by then. Avoid scheduling it for Monday or Tuesday entirely, the preserve is closed both days for reef recovery.
Five days is the itinerary where Honolulu stops feeling like a checklist and starts feeling like an actual trip; the water at Hanauma Bay is the reward for waiting.
