Land of the Yankee Fork State Park near Challis preserves the gold-rush history of central Idaho's Yankee Fork country. Rather than a single site, the park ties together several historic places that show how miners, merchants and families lived in the late 1800s and early 1900s. Visitors can explore the ghost towns of Bayhorse and Custer and see the huge Yankee Fork Gold Dredge, which once churned up the river valley in search of gold. A visitor center in Challis provides context and helps plan a tour of the area. Entry is $5 per vehicle, and camping is $15 to $50 per night, though some tours may have separate costs. It is a great stop for history buffs and families who enjoy old mining towns.
