Know Before You Go

Green Bay National Wildlife Refuge islands are currently closed to the public. Plum island is only open for limited special events but after recent completion of a comprehensive conservation plan, is approved to open to the public for day use (hiking, wildlife observation, photography). However, in order to offer safe and quality experiences to refuge visitors a number of projects must first be completed. Plum Island is planned to open to visitors during summer of 2014 - date TBD. Hog and Pilot Islands are closed to the public and will remain so in order to reduce disturbance to nesting birds.
