About this program

Explore a little-known part of the park and tour a cabin camp built in the 1930s. Join park rangers at Cabin Camp 2 at Prince William Forest Park to learn more about the period of the park’s history in the 1940s when the Office of Strategic Services (OSS) trained spies in the park.

Take a rugged two mile hike off-trail with a ranger to an old OSS training ground at 9:00 am or 12:30pm and/or tour the cabin camp to learn more about the OSS. Hikes are limited to 30 visitors each and first-come, first-serve free tickets for the hike will be available at the event at Cabin Camp 2 starting at 8:30am. Unfortunately, the off-trail hike is inaccessible to wheelchairs and strollers. It is recommended to wear long pants and hiking shoes if planning to do the off-trail hike.

Guided cabin camp tours are offered to visitors after each hike and are open to all visitors. Visitors are also welcome to do a self-guided tour of the cabin camp anytime between 8:30am and 3:00pm. The cabin camp gates will close at 3:00pm.
