Beautiful scenery and numerous recreational opportunities surround historic Katahdin Iron Works, including Gulf Hagas, a stunning gorge more than three miles long, which carves through slate bedrock. Gulf Hagas is a National Natural Landmark and part of the Appalachian Trail. Nearby, the Maine Chapter of the Nature Conservancy protects 35 wooded acres of some of Maine’s oldest white pines. Known as The Hermitage, this preserve is also a National Natural Landmark.
