Know Before You Go

Plum Island is open to public use during daylight hours Memorial Day weekend through Labor Day weekend for hiking, wildlife observation, and nature photography on designated trails and beach areas only. 

Kayaks, canoes, and dinghies may access Plum Island at the designated landing area (near boathouse on northeast side of Plum Island).

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. 

NOT PERMITTED on Plum Island: fishing from the dock (shoreline fishing is permitted); swimming from the dock or other structures; collection of plants, berries, seeds, mushrooms, rocks, fossils, antlers, or other artifacts; fireworks; camping; campfires; geocaches; drones.

Pilot, St. Martin, Rocky, and Hog Islands (Green Bay NWR) and Spider and Gravel Islands (Gravel Island NWR) are closed to public access for use by nesting birds. Please maintain ¼ mile distance from these islands to minimize disturbance to the birds and their nests/young. 

 

The 148-acre parcel on Detroit Island is open for general public use during daylight hours Memorial Day weekend through Labor Day weekend for hiking, wildlife observation, and nature photography. Access is via boat only. Dogs are welcome but must be leashed and pet waste picked up and removed. Refuge land on Detroit Island is also open for white-tailed deer hunting according to state regulations and state seasons. No special refuge permit is required. Access is by boat, and may not exceed one hour before or one hour after legal shooting hours. The parcel is located on the west shoreline at coordinates: N 45o 18’ 17.7” W 086o 54’ 11.6” and is posted with boundary signs and has a boot brush station required for use to reduce the spread of invasive species. Shoreline landing by water craft is best approached with caution due to rocky waters and gravel and driftwood shoreline. Refuge boundary signs are posted on all sides, and refuge staff ask that you please respect the private lands owned on the southwest and northern boundaries of the refuge owned parcel. There are no facilities or restrooms to accommodate visitors, and use is best described as primitive.
