Monocacy National Battlefield comprises 1,647 acres of farmland, forest and riparian areas a few miles south of Frederick, Maryland in the Monocacy River valley. The park encompasses six component properties including the Baker, Best, Lewis, Thomas, and Worthington Farms, as well as the Gambrill Mill and House.
The visitor center has been relocated from the historic Gambrill Mill to a new facility on the west side of the Monocacy River. It offers an electric map orientation program, an interactive computer program, interpretive displays, and artifacts of the battle. The visitor center is the starting point for a self-guided four-mile auto tour and 1/2 mile loop walking trail. National Park Service rangers and volunteers host battle walks, special programs, an auto tour and special events throughout the summer season. The interpretive Worthington Farm Trail allows the visitor to walk parts of the battlefield and explore the native flora of the region.
