Big Springs to Bear Pond Professional Review and Guide
"The unique natural and man-made features found along the route combined with the outstanding riding terrain make this ride truly stellar. Beginning in the valley at Big Springs State Park, the ride runs out on incredible singletrack trail to the old Path Valley railroad tunnel.
This classic example of old-school tunneling stands as a reminder of the hard work and labor involved in running railroads through the Pennsylvania mountains. The unfinished tunnel is not that deep, about 300 feet, and the roof is somewhat unstable, so please stay behind the wooden fence. Highlights: Tuscarora sandstone technical sections, the historical Path Valley railroad tunnel, restrooms and beautifully wooded picnic area, classic ridge and valley riding. Tread: a true mountain bike mix covering singletrack, doubletrack, and fire roads."
