Know Before You Go

Green Bay National Wildlife Refuge islands are closed to the public. Hog and Pilot Islands are closed to the public to reduce disturbance to nesting birds. Plum Island is currently closed to the public except for special events but after recent completion of a Comprehensive Conservation Plan, is planned to open to the public for day use (hiking, wildlife observation, photography) between Memorial Day and Labor Day in 2014. Hog and Pilot Islands will remain closed.
