Harbison State Forest is a large wooded area bordering the Broad River in northwest Columbia. While there are numerous trails and trailheads, the main access point is just off of Broad River Road (176). The Firebreak Trail is the most runnable trail in the park. It’s a moderate 4.4 mile loop, which mostly follows dirt doubletrack. All other park trails connect to the Firebreak, so feel free to explore your options. The Eagle Trail and the Discovery Trail both make good additions.
