Stroll along Donkey Trail, which is elevated 5 feet, or so above the ground giving you a bird's eye view of the forest. The trail got its name because donkeys would haul carts filled with ore from the mines to the furnaces along iron rails that once lined this path. The rails were removed for scrap during World War II.
Soon, you will come to a small pond formed by damming Mineral Brook to create a reliable water supply for the ironworks. Underground pipes connected the pond to at least three hydrants placed at strategic points throughout the complex. Here, you can take an optional 3/4 mi. loop on a yellow blazed Nature Trail.
