Before you go

Parking

Start at Temple Hill Trailhead on Houchin Ferry Road. The gravel lot is small; its capacity and overflow options were not documented.

Safety

Expect steep, rocky gullies and short climbs. Informal paths can be hard to distinguish from the marked route; check the current park map, especially near the rock ledge around mile 4.25. Confirm which proposed trail-plan changes are in effect.

“Temple Hill Trailhead is ahead, for McCoy Hollow's wooded ridges and creek ravines. I'd save this for a planned backcountry hike: steep, rocky gullies and repeated climbs make it more than a casual forest stroll.”

Hiking McCoy Hollow Trail

A point-to-point backcountry walkMcCoy Hollow Trail is a 6.

McCoy Hollow Trail is a 6.4-mile, one-way walk from Temple Hill Trailhead to a junction with Wet Prong Trail. The route follows wooded ridges above creek ravines; it is a rough backcountry traverse, not a loop. Allow about three to four hours one way. The far end is another trail junction, not a parking lot, so arrange a ride or return along the same path for a 12.8-mile day.

Rocky footing and tricky turnsThe trail drops through a narrow, rocky gully near Temple Hill, then rises and falls along…

The trail drops through a narrow, rocky gully near Temple Hill, then rises and falls along ridges around several ravines. Expect uneven tread, short steep climbs and eroded edges. A 2024 trail account describes a sharp left turn near a rock ledge around mile 4.25, while an unofficial path continues straight. A 2021 inventory counted 123 visitor-made paths in this corridor, some hard to distinguish from the marked trail. Carry the current park map and stay on the designated line.

A backcountry campsite on the wayThe hike-in McCoy Hollow campsite branches off the route about 4.

The hike-in McCoy Hollow campsite branches off the route about 4.3 miles from Temple Hill, including its short spur. It is a separate, single campsite rather than a trail facility; check current backcountry and reservation rules before planning an overnight.

The park's current backcountry list still describes the full Temple Hill–Wet Prong corridor as 6.4 miles. A 2024 trail-plan draft proposed retiring 2.3 miles, and I could not confirm which changes have been completed on the ground. Check the latest park map before relying on the entire route. Leashed pets are allowed on park surface trails; keep them on a leash no longer than six feet, and give horseback riders room to pass.
