About Sand Bridge
Sand Bridge State Park in Union County provides day-use recreation in the limestone valleys of central Pennsylvania. The park takes its name from a natural stone bridge formation — one of several geological curiosities in the Ridge and Valley Province, where 450-million-year-old limestone has been sculpted by water into bridges, caves, and sinkholes. The surrounding farmland is some of the most productive in the eastern United States.
Things to Do
Picnicking, viewing the natural stone bridge, hiking, fishing in nearby limestone spring creeks (excellent trout habitat), and exploring the geological formations of central Pennsylvania’s Ridge and Valley landscape.
Getting There
Located off Route 487 near Benton in Columbia County — in the Appalachian Ridge and Valley region of northeastern Pennsylvania. The park provides hiking and nature study in the Fishing Creek watershed. The area sits on the Allegheny Front — the dramatic escarpment separating the folded Appalachian ridges from the Allegheny Plateau. Covered bridges dot the surrounding rural landscape.
History & Ecology
The park takes its name from a natural sandstone formation spanning Fishing Creek — a geological curiosity in the Ridge and Valley region. The surrounding North Mountain landscape features dramatic fold geology visible in road cuts and stream valleys. Columbia County’s covered bridges (including several on the National Register) make this a scenic day-trip destination.

Frequently Asked Questions
Why does Pennsylvania have so many covered bridges?
Pennsylvania has 200+ covered bridges — more than any other state. They were built to protect the wooden deck from weather, extending the bridge’s life from 10 to 80+ years. The abundance reflects Pennsylvania’s 19th-century prosperity and its many rivers and streams. Today, covered bridges are beloved landmarks — many are on the National Register of Historic Places.
