The access point to the breathtaking Castle Creek Valley is the ghost town of Ashcroft, a silver-mining town founded in 1880. What remains are mostly miners cottages (log cabins with tin roofs), a couple of broken-down wagons stranded in the waist-high grass, a post office and a saloon.

At its height in 1893 about 2500 people worked here, but the silver veins were quickly exhausted and by 1895 the town's population plummeted to 100 residents. To get here, drive half a mile west of town on Hwy 82 to the roundabout and follow Castle Creek Rd south for 12.2 miles.
