Best time to visit Sizerville State Park

Late spring through early fall, roughly May through October, is the best window for RV travel to Sizerville. Summer brings warm days ideal for the pool and creek fishing, while September and October offer cooler temperatures, vivid fall foliage, and prime elk-viewing in the nearby Elk Range. Shoulder seasons can bring wet weather and cool nights, so RVers should plan for mountain-climate swings. Winters are cold and snowy, the campground is closed, and only day-use access is available.

How to get to Sizerville State Park

The park is roughly 6 miles north of Emporium, Pennsylvania, on PA Route 155, about 2.5 hours northeast of Pittsburgh and around 3 hours from Buffalo, New York. Access roads wind through the Allegheny Plateau with steep grades, curves, and long rural stretches, so RV drivers should plan fuel stops and watch for logging trucks and wildlife. There are no low tunnels on the main approach, but secondary forest roads are unsuitable for large rigs. The nearest regional airports for fly-and-rent trips are Bradford Regional and Williamsport Regional, with larger service out of Pittsburgh.
