The Roaring Camp & Big Trees Narrow Gauge Railroad is a 3 ft (914 mm) narrow-gauge tourist railroad in California that starts from the Roaring Camp depot in Felton, California and runs up steep grades through redwood forests to the top of nearby Bear Mountain, a distance of 3.25 miles (5.23 kilometers).

[3] Roaring Camp Railroads operations began in 1963 under the guidance of F. Norman Clark (1935–1985), who was the founder and owner.

[4] In 1958, Clark found the engine Dixiana abandoned near a coal mine in the Appalachian Mountains; he described it as looking like a " rusty pile of junk".

[3] Originally, two large trestles formed a "corkscrew" loop at Spring Canyon, but these were destroyed by a 1976 fire (alleged to have been arson), the smoke from which could be seen from San Francisco.

[5] Clark's wife, Georgiana, Vice President of Operations assumed the ownership and management responsibilities following his death on December 2, 1985.
