The Potter Marsh Wildlife Sightseeing Trail may be the best place to go to see Alaskan wildlife. The 564-acre freshwater marsh stretches for nearly two miles between the New Seward Highway and the base of the Chugach Mountains, creating a maze of wetlands with at least 130 species of migratory birds and nests and 1,550 feet of beautiful, family-friendly boardwalks; This rich habitat also attracts elk, beavers, muskrats, eagles, and salmon.
