This gorgeous park has more than 20 miles of trails that are perfect for family biking. As a child, I lived close enough to Valley Forge that my family would bike there a lot on the weekends and in the summer time. I have great memories of coasting down the rolling hills and stopping at the different monuments and cabins to take a look. There are plenty of picnic areas for eating and taking a rest as well as many other scenic and historical stops along the way. Valley Forge Bikes is located within the park and offers a variety of bike rentals for everyone in your family.
