William B. Umstead State Park: Oak Rock and Pott’s Branch Trails Professional Review and Guide
"William B. Umstead State Park is tightly nestled among the cities of Raleigh, Cary, Durham, and the Research Triangle Park. The park is divided into two sections: Crabtree Creek in the north and Reedy Creek in the south. This route combines two popular trails in the park, the Oak Rock Trail and the Pott’s Branch Trail, to make an enjoyable loop that follows along the Pott’s Branch stream and provides access to a spur trail that leads down to Big Lake. The route starts at the Oak Rock Trail, which loops around through a beautiful forest. It then connects with the Pott’s Branch Trail, which descends to Pott’s Branch and follows alongside the winding creek, eventually reaching the southern edge of Big Lake. From here the trail turns to the north and leads away from the lake, returning to the trailhead."
