Honolulu in 3 Days on a Budget (With Daily Costs)
Three days: Waikiki, Pearl Harbor, then Diamond Head
Three days is enough to add a genuine hike to the 2-day plan’s free beach day and Pearl Harbor reservation. This version keeps the same spine, arrival and Waikiki on day one, Pearl Harbor and downtown on day two, then adds Diamond Head on day three for panoramic views and a $5 entry fee. If you only have two days, drop back to the 2-day version ; with a fourth day to spare, the 4-day plan adds Hanauma Bay.
Book these before you go
- Reserve Pearl Harbor on recreation.gov , up to 56 days out, about a $1 fee.

Day 1: land in Waikiki and keep it free
Fly into HNL and take TheBus routes 20 or 303 for $3 on a HOLO card (about 45-60 minutes) or a taxi/rideshare for $35-50. Check into a Waikiki hotel and budget for resort fees ($45-61/night) and self-parking ($45-75/night) up front, since neither shows up in the quoted rate. Spend the afternoon on Waikiki Beach itself, free to swim or sunbathe on, and grab reef-safe sunscreen if you didn’t pack it, required by Hawaii law. At sunset, catch the free hula and torch-lighting show at the Kuhio Beach hula mound.
Day 2: Pearl Harbor and downtown Honolulu
Arrive an hour before your reserved slot; the USS Arizona Memorial program is free, runs 45 minutes, and only the recreation.gov booking and the National Park Service’s separate $7/day parking charge cost anything. In the afternoon, walk the free grounds of Iolani Palace, then into Chinatown for a plate lunch, $12-18 at most local counters.
Day 3: Diamond Head hike and Ala Moana
Hike Diamond Head early, before the heat and the crowds build: it’s a 0.8-mile trail one way, 1.5-2 hours round trip, $5/person plus $10/vehicle parking for out-of-state visitors, credit card only, reserved up to 30 days ahead. Skip the parking fee entirely by taking TheBus and walking in from the road instead. In the afternoon, cool off at Ala Moana Beach Park, calmer water than Waikiki, then browse Ala Moana Center; a poke bowl runs $12-18 for dinner.
Do you need a rental car for this itinerary?
No. TheBus reaches Pearl Harbor, Diamond Head, and Ala Moana directly from Waikiki, and Diamond Head’s own parking fee is one more reason to skip driving there. A rental car adds $40-60/day plus tax and competes with hotel self-parking that already costs $45-75 a night; it only earns its keep once a North Shore or windward-side day gets added to the trip.
Is Diamond Head worth doing on a short trip?
Yes, more than Hanauma Bay is on a trip this length. Diamond Head’s 30-day reservation window is easier to hit than Hanauma Bay’s 2-day, 7am HST window, the hike itself takes half a day rather than a full one, and the summit view over Waikiki and the Pacific is the single best panorama available on this itinerary’s budget.
Book Pearl Harbor first, then Diamond Head once your dates are firm; both need advance reservations, and neither allows a walk-up. For more cheap and free picks beyond these three days, see the Honolulu budget guide .
