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 (6 km) auto tour and 1/2 mile (800 m) 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, a pair of loops (one nearly two miles (3 km) long, the other 1.6 miles (2 km)) on the northern portion of the battlefield, allows the visitor to walk parts of the battlefield and explore the native flora of the region.
