Narrow but more than a mile long, the Mill House Natural Area is located between the Black River and Black River Road, just north of the McCann Mill Road bridge.  Pull-off parking is available along Black River Road.  Visitors can enjoy passive recreation activities, including fishing, hiking, kayaking/canoeing and nature observation. The river and riparian forest are home to many species, including  great blue herons, kingfishers, great horned owls, ducks and woodpeckers.

Learn About Mill House Natural Area 

This 78-acre property–jointly owned and managed by Raritan Headwaters, Bedminster Township and the New Jersey Water Supply Authority–consists of more than a mile of forested riparian habitat along the Black River.  The land is managed to protect and preserve the quality and quantity of ground and surface water resources and natural habitat. It is part of the Black River Greenway which stretches between Hunterdon, Morris and Somerset counties.  Originally preserved in 2005 when it was conveyed to the Lamington Conservancy and its partners by Millhouse Realty Associates LP, the property has been managed since 2007 by a partnership between Bedminster Township, the New Jersey Water Supply Authority and Raritan Headwaters Association.
