The museum is 6.5 miles east of the Nisqually Entrance on the main park road. The main Longmire lot behind the museum, inn and store has about 80 spaces. There’s no restroom inside the museum; a public building with flush toilets and running water sits between it and the historic gas station. The museum itself has no food service, but the adjacent National Park Inn has a restaurant and coffee at its front desk.
Paved paths can be steep and uneven, and the narrowest museum doorway or walkway is 29 inches wide. There’s a lower accessible section at the information desk. Longmire has no cell service; Wi-Fi is available on the museum porch.
