The upper portions of the trail were originally built in 1876 when rumors of placer gold led speculators to need a way into the area. Further trail work was performed beginning in 1925 under the US Forest Service and continued under the National Park Service with the final sections to Tapeats Creek completed in 1939. The trail was closed to all motorized vehicles effective July 1, 1962 due to safety concerns for both vehicle riders and hikers.
