Trough Creek State Park

Tourist attraction · James Creek, Pennsylvania
Camping nearby

A 541-acre gem in south-central Pennsylvania where Great Trough Creek carves through a scenic gorge in Terrace Mountain before emptying into Raystown Lake. The park's most famous feature is Balanced Rock — a boulder hanging precariously off a ledge throughout recorded history. Rainbow Falls, a 15-20 foot cascade on Abbott Run, is best after heavy rain. A swaying suspension bridge crosses the creek, and the yellow-orange Copperas Rock overhang showcases weathered iron formations. Rugged trails with excellent overlook views.

About this map

Every pin is a live reading from a USGS real-time monitoring station, captured in a daily snapshot. Colours follow the site’s cold-water-safety thresholds and describe the water at that one sensor — usually a river or stream gauge, not a swim beach — so treat them as a guide to what the water is doing nearby, not a verdict on a specific spot. Readings are provisional and can be revised by the USGS. Your location only sorts this page: the coordinates appear in the address bar (rounded to about a mile) and are not saved to an account or our database.

Conditions are for general information only and can change quickly. Always judge the water in person and follow posted advisories and local guidance before swimming or paddling.
