This is a fairly rugged 6-mile hike through the Prairie Grasses and along the Chestnut Oak Trail. There is a 600-foot elevation gain. There are great views of the Lehigh River and our autumn foliage along the way, as well as a close-up look at our prairie grasses. Bring water and a snack and wear sturdy shoes. This hike is a cooperative event with the Allentown Hiking Club.
