Hiking at Colonel Denning State Park

Two trails lie entirely inside that park while hikers can also access many miles of trails in the adjoining Tuscarora State Forest.

Doubling Gap Nature Trail

1 mile, more difficult hiking

This self-guiding nature trail is mostly level and begins and ends at Doubling Gap Lake.

The trail features several interpretive waysides explaining the natural history found around a mountain stream.

Flat Rock Trail

2.5 miles, most difficult hiking

The park acts as the trailhead for the 2.5-mile Flat Rock Trail which leads to the top of Blue Mountain in Tuscarora State Forest.

The steep and rocky trail is worth the effort; it culminates at Flat Rock, a natural rock outcrop that provides a beautiful scenic vista of the Cumberland Valley.

Rattlesnake Trail

1 mile, more difficult hiking

Rocky in places, this trail winds through a mixed oak forest on the foothills of Blue Mountain.

Tuscarora Trail

105 miles, trailhead access only

The 105-mile Tuscarora Trail is the northern portion of a 220-mile bypass of the Appalachian Trail.

The Hiking and Nature Trail Guide available at the park office has maps and detailed descriptions.
