Swatara State Park: Rail Trail/Bear Hole Loop Professional Review and Guide
"After a short walk along Swopes Valley Road, this hike picks up the Swatara Rail-Trail and follows it northwest for 3 miles to the Sand Siding Trail. Here the hike heads to the west, crossing the new bridge over Swatara Creek. After crossing the creek, the hike picks up the Bear Hole Trail and follows it for 3 miles back to the parking area.
Located in Lebanon and Schuylkill Counties, the 3,520-acre Swatara State Park is a mostly undeveloped park that provides opportunities for a variety of activities, including hiking, biking, fishing, canoeing, and hunting. An 8-mile section of Swatara Creek flows the length of the park, exiting at its southern boundary in Swatara Gap, a large water gap through the flank of Blue Mountain. Interstate 81 passes through the gap directly above the creek, as does the Appalachian Trail (AT) directly beneath I-81."
