Steeped in natural and historical features, the 696-acre Pine Grove Furnace State Park is at the northern tip of the Blue Ridge Mountains in an area known as South Mountain. Visitors enjoy many recreational opportunities  including two mountain lakes (Laurel Lake and Fuller Lake), hiking the Appalachian Trail and biking the rail trail.  Visit the Appalachian Trail Museum and imagine when the park was a charcoal-fired iron furnace community.

The park is surrounded by Michaux State Forest, which provides opportunities for exploring extensive public lands around South Mountain.
All park roads and service roads are open to bicycles unless posted otherwise. The two-mile Cumberland County Biker-Hiker Trail connects the Furnace Stack Day Use Area with Laurel Lake Day Use Area.

Pine Grove Furnace State Park marks the midway point along the 2186 mile long Appalachian Trail. Obeying tradition, hikers eat a half-gallon of ice cream here. Although no camping on the trail is permitted within the park boundaries, visitors can stay overnight at the Ironmaster’s Mansion located on the trail in the park for public use. The park is also a popular staging point for short term backpacking on the AT with a 20 mile hike north to Boiling Springs or south to Caledonia.

Camping and hiking are popular activities. Campground facilities have been recently upgraded with 70 tent and trailer sites. Hike up to Pole Steeple Vista to view the eastern part of the park from the overlook. Visit the Fall Furnace Festival and see hundreds of jack-o-lanterns float on Fuller Lake! So much to do at this must-see PA park!
