Trail Rating: Rugged

Turkey Pen Hollow Trail passes through high quality dolomite glades and woodland plant communities. The area in and around this trail is managed with periodic prescribed fire. Information on this fire management is available at the trailhead and at the park office. The trail also takes hikers and backpackers past a large sinkhole, to an access to the park’s special-use camp, a primitive backpack camping area for large groups, and meanders through Turkey Pen Hollow. Hikers often spy deer and turkey along the trail, and if not the real thing, evidence of their tracks and droppings.

After passing the connector trail leading to the special-use camp, hikers will travel across a large south-facing glade. Lower on this slope is an intermittently wet seep area. Ahead, a large outcrop of rock is the remnant of the Red Arrow Fault line that runs through this part of Camden County. This interesting rock area is where layers of bedrock have shifted in a vertical manner and in other places one layer of rock has shifted pushing other rocks layers above it.

After reaching the ridge top and hiking for a short distance, hikers can chose to shorten their hike to 4.75 miles by taking White Connector 1. Along White Connector 1, there is an intermittent pond. This pond, which often holds water in the spring, is home to many frogs, salamanders and toads as evidenced by the cacophony of their calls both during the day and in the evening.  

The primitive backpack camping area for groups of seven or more is located on the two-mile segment of trail after you reach the ridge top, and is in a sheltered valley on the east side of this trail.

Follow the red blazes counterclockwise to hike Turkey Pen Hollow Trail. Turkey Pen Hollow Trail was built by park staff and volunteers in 1997.
