Free things to do on Oʻahu
26 places that cost nothing to get into — museums, beaches, trails, gardens and landmarks. Where something still costs money, like parking or a reservation, it says so on the same line.

Free events worth planning around
Listed as free, but not
The Honolulu Fish Auction tour
Listed as free all over the internet. It is $35 for adults and $25 for children 8–12, reservation only, on selected Saturday mornings from 6am. Worth doing — just not free.
The Aloha Tower observation deck
Free when it is open, but it has been closed since 2020 for elevator, fire-suppression and structural work. Reports of a 2026 reopening exist but we could not confirm one from an official source. The marketplace below is open and free to walk.
Free hula lessons at the big hotels
The Hilton Hawaiian Village’s hula, ʻukulele, lei-making and yoga sessions need a guest activities card. Only the Friday fireworks is open to the public. For genuinely free lessons, go to Royal Hawaiian Center in Waikīkī instead — those are open to anyone.
“Free” state park lookouts
Entry is free at Nuʻuanu Pali and Puʻu ʻUalakaʻa, but non-residents pay $7 a vehicle to park at each, and Puʻu ʻUalakaʻa only started charging in February 2026.
Kualoa Ranch
Often confused with the free county beach park across the road. The ranch itself is entirely ticketed, from about $55. Kualoa Regional Park, with the Mokoliʻi view, is the free one.
