Colonel Denning State Park
Surrounded by rolling mountains, Colonel Denning State Park's 273 acres of woodland is the perfect place to enjoy a little peace and quiet. With the 3.5-acre Doubling Gap Lake for swimming and boating in the summer and ice-fishing and ice-skating in the winter, a 52-site campground, volleyball, picnicking and trails for hiking, biking and horseback riding, it's the perfect place to bring the family and connect with nature.
Things to Do at Colonel Denning State Park:
There are 3 trails totaling 3.5 miles to explore in Colonel Denning. The most notable trail is the 2.5-mile (one-way) Flat Rock Trail. The strenuous, rocky climb leads to a 180-degree panoramic view of the Valley. In the fall, enjoy the foliage and hawk migration from the Flat Rock lookout. The trail head is located next to the Visitors Center. The self-guiding Doubling Gap Trail is a one-mile moderate hike.
Colonel Denning is a trail head for Tuscarora State Forest and the 252-mile Tuscarora Trail. Trails in the surrounding Tuscarora State Forest are accessible from the park and when combined with those in the park provide 13 trails with 18 miles to explore.
Cycling is allowed on paved roads through the park (approximately 1 mile). View additional Cumberland Valley bike routes.
The park has an equestrian trailhead where riders can access the state forest trails.
