The preserve, marked by a large sign, is located in Newcastle on the right side of US Route 1 as you are headed southbound just beyond the Snead Spur, which joins US Route 1 and River Road. Take a right off of US Route 1 and pull back into the parking area among the tall pines. Northbound, look for a car dealer, Mike’s Place, and Freedom Fuel – continue a  few hundred yards and turn left into the shared dirt drive to park.


Cotton grass, bog orchids, cranberries, and stunted trees cling to a mat of peat moss which forms an ‘island’ in the center of the bog.

Numerous individuals, foundations and public funds made the acquisition possible, among them the Maine Outdoor Heritage Fund, supported by the purchase of special instant lottery tickets, a North American Wetlands Conservation Act grant, the Fields Pond Foundation and the Falcon Foundation.
