The trail begins at the Pole Steeple parking lot, along the Railroad Bed Road by Laurel Lake, and proceeds up Piney Mountain to the rocky overlook.

The steep grade and sheer drop may stress some individuals. Parents are advised to closely supervise children, especially when they are on the rocks and ledges.

0.25-mile, yellow blazes, easiest hiking

This short trail circles a small, forested swamp filled with interesting plants and animals. The trail begins and ends on the rail trail.

Appalachian Trail (National Scenic Trail)
Running through the heart of the park is probably the most famous footpath in the world, the Appalachian TrailOpens In A New Window (AT). The 2,186-mile long trail traverses the Appalachian Mountains, stretching as a continuous footpath from Springer Mountain in northern Georgia to Mt. Katahdin in central Maine.

The trail is marked with white blazes, which can be seen near the Pine Grove General Store, Appalachian Trail Museum, Fuller Day Use Area, and on the rail trail.

Half-Gallon Challenge
About 2,000 people attempt to hike the entire AT in one year. These long distance hikers are called thru-hikers and most pass through the park from late spring through the summer months.

About one out of four thru-hikers will complete the whole trail. Reaching Pine Grove Furnace State Park is a milestone. The halfway point of the AT is several miles south of the park, in Michaux State Forest.

To commemorate the completion of half of the journey, it is a thru-hiker tradition to attempt the “half-gallon challenge” of eating one half of a gallon of ice cream in one sitting. On a summer day, it is common to see hikers working on the challenge at the Pine Grove General Store.

Hiking the Appalachian Trail
The Appalachian Trail is a popular destination for short-term backpackers and day hikers. About two to three million people walk a portion of the AT each year.

Pine Grove Furnace State Park is a popular staging point for short-term backpacking on the Appalachian Trail.

Boiling Springs to the north and Caledonia State Park to the south are each about a 20-mile hike from Pine Grove Furnace.

Overnight parking is available for backpackers in a special section of the Furnace Stack parking lot. Hikers should register their car and supply contact information and an itinerary at the park office.

Information, maps, guides, shuttles, and more are available.

Wildlife Watching at Pine Grove Furnace State Park

The diverse habitats of Pine Grove Furnace State Park support a variety of wildlife through all seasons. The historic use of the area during the iron furnace period created a varied combination of open areas, wetlands, and vegetation that make the area unique for wildlife.

Spring and fall is the time of bird migrations. The forest, interspersed with ponds and wetlands, makes the park a rest stop for many migrating forest birds. Warblers, vireos, and thrushes stop to rest and eat before flying on to their breeding or winter homes.

Laurel Lake and its shoreline wetlands are a beacon that lures waterfowl. Merganser, Canada goose, mallard, loon, teal, and many other ducks can be seen swimming, diving, and dabbling for vegetation and small fish. Wild turkey and woodcock call from open areas.

Winter is a good time to see woodpeckers and evidence of their presence. Pine Grove Furnace has at least six species of woodpeckers.

Summer is the time of lush green vegetation and growing young animals. In thickets and along roads, watch for spotted fawns and frantic bluebirds searching for food to feed their hungry chicks. Butterflies reach their peak numbers and can be seen floating from flower to flower in the fields and wetlands.

During the fall, the deciduous trees lose their chlorophyll and their leaves reveal beautiful reds, oranges, and yellows. This is a time that many animals are preparing for the winter season ahead. There is a growing population of black bears in the area and visitors may see one putting on weight for the winter hibernation. Beavers may be seen working on lodges and dams in the upper channels of Laurel Lake at twilight.
