Prime Hook was established in 1963 as part of the Migratory Bird Conservation Act. Located about 20 miles south of Dover, the Refuge serves as an important stopover site for migratory birds, offering protected breeding habitat to many endangered species. Visitors can see forests, grasslands, salt marshes, ponds and swamps. The Refuge offers hunting, fishing, wildlife observation and photography, and is home to 51 species of fish and 45 species of reptiles and amphibians. The Refuge is open to the public every day from a half-hour before sunrise to a half-hour after sunset.
