This trail provides access to the historic Mountain Quarries Railroad Bridge (built 1912), a notable concrete arch landmark spanning the North Fork American River between El Dorado and Placer counties.

The trail is relatively easy and level, following an old railroad bed, with a safer, wider spur trail leading down to the river's edge for swimming and picnicking.

The area offers scenic river views and is popular with hikers, runners, and horseback riders, though it has minimal shade and can get very hot—bring plenty of water and sun protection.
