This trail includes both the Jacobs Hollow and Round Island Run trails, both in Sproul State Forest, PA. The total mileage, one-way is 3 miles.

The first section of the hike is Jacobs Hollow, which is mostly flat and leads down to the Round Island Run trail.

The hike down on the Round Island Run trail is fairly steep and then disappears half way through the journey toward the river. Either the overgrowth made it hard to spot the trail, or the trail crossed the creek and we didn't realize.

Prepare to cross brooks multiple times before making it down to the river. Small waterfalls can be found along the Round Island Run trail toward the river as well.

Road Conditions: Jerry Ridge Rd and the roads leading to it are all dirt. These roads can often be extremely muddy during the rainy seasons and if you're not careful, your car could get stuck. There's also no cell service for dozens of miles. If you plan to drive in, it's often an 11-mile one-way drive to get to the trailhead, so come prepared with a vehicle that can handle these conditions.
