- Trekking Poles: Highly recommended for navigating the steep, rocky sections.
Hunting Season Safety: During hunting season (primarily November-December), hikers should wear at least 250 square inches of fluorescent orange material on the head, chest, and back combined, or a fluorescent orange hat when hiking through state game lands.

Local Customs
The Appalachian Trail has its own culture and customs. If you encounter thru-hikers (those hiking the entire 3,500 km/2,190 mile trail), it’s customary to offer encouragement. Many hikers use trail names rather than their given names, and there’s a strong ethic of helping fellow hikers in need.
Visitor Comments About Peters Mountain
“The Peters Mountain Loop challenged me more than I expected for a ‘short’ hike! The rock scrambles were difficult but the views of the Susquehanna made every step worthwhile. Bring trekking poles and plenty of water – you’ll need both.”
“We timed our visit for peak fall foliage in October and were rewarded with the most spectacular colors. Table Rock offered the perfect spot for lunch with a view. Don’t miss talking to the thru-hikers if you get the chance – their stories are fascinating!”
“As a wildlife photographer, Peters Mountain exceeded my expectations. I spotted several species of raptors migrating along the ridge and even caught a glimpse of an elusive Allegheny woodrat. The morning light at the river overlooks creates perfect conditions for photography.”
