Voorhees, like Parvin State Park, served as a camp for the Civilian Conservation Corps (CCC) - Franklin Roosevelts program to get people back to work during the Depression. The CCC planted trees and constructed shelters, picnic sites and trails throughout the park.
Only one main trail you can ride. Partly single track and it's a quick lap. Can do it in 10 to 15 minutes tops. Does have a pretty hard climb with log steps if you go counterclockwise. Great learning course for beginners or after work for a quick ride.
