Green Bay National Wildlife Refuge consists of Hog Island, Plum Island, Pilot Island St. Martin Island, and Rocky Island. The islands are located in Lake Michigan, near Washington Island, off the tip of Wisconsin's Door County Peninsula.
The refuge is managed by staff at the Horicon National Wildlife Refuge Complex in Mayville, WI. Contact 920-387-2658 or firstname.lastname@example.org.
Plum Island will be open during daylight hours Memorial Day weekend through Labor Day weekend (May 23-September 7, 2015) for hiking, wildlife observation, and nature photography on designated trails and beach areas only.
Due to current dock condition and limited dock space, boats will not be allowed to dock. Only kayaks, canoes, and dinghies will be authorized to access Plum Island at the designated landing area (near boathouse on northeast side of Plum Island) until further notice. Special event days planned by the Friends of Plum and Pilot Islands, the U.S. Fish and Wildlife Service, and other partners will offer transportation via charter service on those days. (See the events schedule below for more information)
Foot travel only on the island (no motorized vehicles or bicycles) and use of boot brush station is mandatory to prevent the spread of invasive species. Dogs are welcome but must be leashed and pet waste picked up and removed.
