On Schofield Barracks in Oʻahu, the Tropic Lightning Museum traces the history of the post, Wheeler Army Airfield and the 25th Infantry Division. Inside, era-by-era displays bring together uniforms, tools, photographs and other military artifacts, with a scale model of a Viet Cong tunnel among the more immersive exhibits. Outside, you can view tanks and other vehicles. Admission is free, but visitors without base access need to arrange entry to the installation before making the trip.
The museum and its collection

The Tropic Lightning Museum is at Schofield Barracks, an Army installation in Oʻahu. Its collection covers the history of the barracks, Wheeler Army Airfield and the 25th Infantry Division, known as Tropic Lightning. Photographs, memorabilia and military artifacts connect the division’s history with the places where it served and trained.
The displays span different periods, with uniforms, tools and equipment arranged by era. The museum also covers the history of Schofield Barracks, including its early years. Some exhibits may not follow a clear chronological route, so give yourself time to look through the rooms rather than relying on a single path through them.
Details to look for inside

Among the more unusual displays is a scale model of a Viet Cong tunnel, shown with rats and a GI flashlight. The exhibit offers a close view of the confined setting represented in the model. First-person accounts are also available to read at the museum; they add individual perspectives alongside the objects and historical information.
The collection is housed in a historic lava-rock building. It once served as the post library, and its construction is associated with prisoners. The building’s past is part of the visit, alongside the exhibits on the base and the division.
Outside the museum
After looking through the indoor exhibits, take time to see the tanks and other vehicles displayed outside. The outdoor collection gives you another way to view military equipment beyond the uniforms, photographs and smaller artifacts indoors.
The museum is on an active Army installation, so reaching it involves more planning than a visit to a museum in town. People without base access need to arrange a day pass and should have identification and vehicle registration information ready. Allow for installation entry procedures before planning the museum portion of your visit.
