Chewacla State Park is a great place to experience a broad range of trail types and styles mixed together to satisfy any type of riding or any skill level.
Few places in the southeast have as wide a range of mountain biking as CSP, which includes standard XC trails, a well groomed and extensive dirt jump area, flow trails, and a wicked feature area complete with a massive wall ride and Oregon-downhill-style 2x4 ramp features. Everything is ridable on a standard mountain bike, but drop that seat low (or off completely) for the dirt jumps! Also, call ahead if you want to get on the dirt jump course to make sure it is open that day.
The trails to the southwest side of the park are more technical and rooty, while the trails at the "back", or east end of the park by the river are more downhill and flow oriented. It takes about half a day to ride the now 27 mi. of trail but many sections are designed to be ridden multiple times as part of more than one loop, which is great because some of the best runs are highlighted.
