Alaska Maritime National Wildlife Refuge protects the habitats of seabirds and marine mammals on the more than 2,400 islands, headlands, and rocks along the coastline from Ketchikan to Barrow.
The 4.5 million acre refuge is a varied blend of rain forest, tundra, cliffs, volcanoes, beaches, lakes, streams, and rivers. More than half of the refuge is wilderness.
About 75% of Alaska's marine birds (15-30 million birds) use the refuge, congregating in colonies along the coast.
Visitor activities include wildlife observation, photography, and bird watching.
