Valley Forge National Historical Park is located about 20 miles northwest of Philadelphia in a populated suburban setting less than 2 miles from the King of Prussia Mall. Most visitors arrive by car or tour bus and drive the 10-mile Encampment Tour route to see the park's nine historical attractions. An 8.7-mile paved multi-use trail parallels most of the driving tour route and accommodates walkers, bike riders, and equestrians. The park does not have a shuttle or transportation system.

Parking at the Visitor Center

Bus Parking
All bus parking is located in the lower parking lot (keep right at the fork when entering the park). Buses may drop off and pick up passengers in front of the Visitor Center, however all buses must leave the drop off area while waiting for passengers.

Accessible Parking
Eight accessible parking spots are available in front of the Visitor Center main entrance. Visitors can enter the Visitor Center at ground level and take the elevator to the second floor to access the Theater.

No Idling Policy
In an effort to improve visitor enjoyment and reduce environmental impact, Valley Forge has implemented a no idling policy for motor vehicles within the park. All motor vehicles that are parked for more than 30 seconds must turn their engines off. This restriction is to reduce public exposure to diesel, exhaust particulate matter, and other toxic air contaminants by limiting the idling of buses, trucks, and other motor vehicles. In addition, this restriction will limit the noise impact on visitors throughout the park. Learn more about park rules and regulations.
