Things to Do

Pennsylvania’s massive state park system is defined by deep hardwood forests, rugged river gorges, and expansive lakes. It offers top-tier hiking on miles of trails (including access to the Appalachian Trail), extensive boating and sailing on natural and man-made lakes, and some of the best fly fishing for trout in the eastern United States. Visitors also enjoy whitewater rafting, camping in shaded forest sites, mountain biking, exploring old-growth forest remnants, and visiting historical sites that chronicle America’s early industrial and colonial history.

Best Time to Visit

Fall (late September through October) is magnificent, as Pennsylvania’s vast deciduous forests put on one of the best foliage displays in the country. Summer (June–August) is the busiest season, perfect for lake swimming and shaded woodland hikes. Spring (April–May) brings high water levels great for whitewater paddling and waterfall viewing. Winter transforms many northern and mountain parks into destinations for snowmobiling, cross-country skiing, and ice fishing, though some park facilities close seasonally.

Visitor Tips

Pennsylvania stands out by offering free admission to all state parks for day use. Camping and cabin rentals require fees and can be reserved up to 11 months in advance through the state’s reservation system. Popular parks like Ohiopyle and Ricketts Glen can get very crowded on summer and fall weekends. When hiking waterfall trails (like the Falls Trail at Ricketts Glen), wear sturdy, grippy footwear as the stone steps are perpetually wet and slippery.
