Remnants of Pennsylvania’s past are scattered throughout the landscape. Some of those abandoned ruins are more well-hidden than others. Each, however, offers a unique glimpse into a time now long gone. This hidden trail in Pennsylvania leads to the remnants of a once-thriving iron furnace.

Hidden in Clear Creek State Forest in Sigel, the Bullion Run Iron Furnace Ruins sit along the Iron Run Furnace Trail.

Tallying just over three miles, the moderately-rated trail features several challenges, including exposed tree roots and rocky terrain. Be prepared for a lot of mud after a rainfall, too.

The highlight of the trail is, arguably, the remains of the Bullion Run Iron Furnace, or Cross’s Furnace.

Charcoal powered the furnace which required more than half a dozen workers, who worked on nearby farms when the furnace temporarily closed during the summer.
