The Todd Wildlife Sanctuary is home to the Seabird Institute’s administrative offices, Mad River Decoys by Audubon and Hog Island Audubon Camp.

Located six miles southeast of Damariscotta on Muscongus Bay, Todd Wildlife Sanctuary includes a 30-acre mainland parcel, as well as 330-acre Hog Island, located a quarter-mile offshore. Visitors are welcome to explore the mainland and island property dawn to dusk, seven days a week, year round. Dog must be leashed on the mainland and are not permitted on Hog Island. Please note that there are no public ferries to Hog Island. Visitors are allowed to beach small vessels on the island, but there are no public boat launches from the Todd Wildlife Sanctuary’s mainland location. Moorings are available on a first-come, first-served basis. No fees are collected for mooring boats and no responsibility is assumed by Audubon for use of moorings.
