On Waikīkī’s western side, Fort De Russy offers a change of pace from the neighborhood’s busiest streets: it is a U.S. Army reservation with parkland, beachfront and the U.S. Army Museum of Hawaiʻi. The free museum is set inside a historic coast-artillery fortification, making this a stop where military history and open space meet.
- Location: 2131 Kalia Road, Fort DeRussy, Waikīkī.
- Museum pattern: Tuesday through Saturday, 10 a.m. to 5 p.m.; closed Sunday and Monday.
- Admission: The museum is free and open to the public; military installation visitor-access rules may apply.
Finding Fort De Russy in Waikīkī
Fort DeRussy sits in Waikīkī, with the museum at 2131 Kalia Road. The reservation was established in 1909 as part of the Headquarters Coast Defenses of O‘ahu, intended to protect Honolulu and Pearl Harbor. Its name honors Brigadier General René E. DeRussy, a 19th-century U.S. Army Corps of Engineers officer.
Because this is an Army reservation, distinguish the museum’s public admission from access to the grounds. A one-day visitor pass is available for infrequent visitors, including museum visitors.
The pass is valid until midnight on its issue date and requires valid REAL ID Act-compliant identification. Non-U.S. citizens must be sponsored by a DoD ID card holder aged 18 or older and escorted by that sponsor at all times.
Allow time to confirm the current entry process before setting out. The U.S. Army Museum of Hawaiʻi says a federal holiday falling on a Monday means the museum will also be closed the following Tuesday.
What to see at the Army Museum of Hawaiʻi
The U.S. Army Museum of Hawaiʻi presents military history through its setting in Battery Randolph and exhibits on Hawaiʻi and the Pacific. The museum was established in 1976 in the former coast-artillery fortification, which once mounted two 14-inch disappearing rifled guns. The museum says the guns were never challenged or fired in anger.
Exhibits cover the U.S. Army in Hawaiʻi and the Pacific, Hawaiʻi’s military history, and the contributions of Hawaiʻi and its citizens to national defense. Topics include the Hawaiian monarchy’s military organizations, Coast Artillery in Hawaiʻi, World War II, Korea, Vietnam, the Go for Broke Nisei Soldiers, and a Gallery of Heroes.
For research beyond the galleries, the museum’s photo archive contains more than 20,000 images, and staff can assist with historical inquiries. Group tours for military and civilian visitors are conducted by appointment.
The museum is free and open Tuesday through Saturday from 10 a.m. to 5 p.m.; it closes Sunday and Monday. As opening hours and access arrangements can change, check the official site before you go.
The Army museum’s focus on Hawaiʻi’s military history gives it a distinct place among museums in Honolulu.
The park and memorial landscape
Fort DeRussy’s grounds combine open space and recreation areas with the military site. The reservation includes park areas, tennis courts, a volleyball court, a picnic area, and beachfront, making it possible to pair the museum visit with time outdoors.
The beachfront is part of the public-use setting at Fort DeRussy. If you are planning a separate shoreline stop, this guide to Waikīkī Beach access points covers another way to plan beach time in the neighborhood.
Adding the fort to a Waikīkī walk
Pair the museum with a walk around the reservation, but keep the installation’s entry rules in mind. The main gate is open 24 hours a day, seven days a week; that does not establish the hours for every park area. Confirm current access details before you go, especially if your plan depends on spending time outdoors.
If you are arriving in Waikīkī from the airport, the trip is a separate planning step from visiting the fort; this guide to getting from Honolulu Airport to Waikīkī covers that connection. From Sweetwater at Waikiki, the fort is about a 24-minute walk or a 6-minute drive; you can pair the visit with the reservation’s beachfront and picnic area.
