A nine-hole golf course was opened in 1922, and has since been expanded to 18 holes. The Pennsylvania Alpine Club paid for the reconstruction of the stack of the old furnace and built a monument. A blacksmith shop, the stack, and numerous charcoal hearths and charcoal roads are visible reminders of the iron-making days. Many of the roads and facilities used today at Caledonia State Park were built during the Great Depression by the young men of the Civilian Conservation Corps (CCC).
