Potter Marsh

A bird lover’s paradise right inside Anchorage

Anchorage’s Potter Marsh is one of the most accessible and scenic wildlife viewing areas in all of Alaska. Potter Marsh is a bird lover’s paradise at the southern end of the Anchorage Coastal Wildlife Refuge. A protected wetland, the 2,300-acre viewing area is just south of the city and has a long, raised 1,550-foot boardwalk from which you may access the wetland without disturbing the birds. There are interpretive signs along the walk. You may also use a pull-out along the Seward highway to access it.

From late April through September, Canada geese, northern pintails, canvasback ducks, red-necked phalaropes, horned and red-necked grebes, and northern harriers use this wetland. Look for eagle nests in the cottonwoods near the base of the bluff using binoculars or a spotting scope. Eagles have a sharp sense of sight and can see at least four times better than people, enabling them to detect movements of small animals like hares from a mile away. When eagles soar overhead, they are scanning open areas for prey.

From May to August, gulls, Arctic terns, shorebirds such as yellowlegs, and occasionally trumpeter swans are present during spring and fall migration.

In addition to birds, look for slow movement and a v-shaped wake in the waters of the marsh, signs of muskrats swimming past. Their small brownish heads peek just above the water as they meander in and out of the wetland’s open areas.

Moose also frequent Potter Marsh year round. May and June are good times to see these large ungulates standing in the marsh foraging for new growth.

About halfway along the boardwalk, Rabbit Creek flows underneath and provides a good spot to see spawning chinook, coho, or humpback salmon from May to August, depending on the species. Spot their bright red bodies swimming in the creek.

With its nearly panoramic view of Turnagain arm, Potter Marsh, buffered by spruce, cottonwoods and alders, is one of the most accessible and scenic wildlife viewing areas in Anchorage.

Spruce, cottonwoods, and alders frame the north and east borders of the marsh. To the south, Turnagain Arm sweeps out to Cook Inlet.

Potter Marsh hosts the greatest number of birds between late April and the end of May. Bald eagles, northern harriers, yellowlegs, Arctic terns, pintails, Canada geese, red-necked grebes, and Pacific loons stay through the summer. Muskrats and moose frequent Potter Marsh year-round; in May and June, look for them in the evenings as they forage on the new green growth.

Viewing and Safety Tips:

Do not disturb nesting waterfowl or migrating salmon. Fishing is prohibited in Potter Marsh and in the creek west of the highway. Visitors should prepare for cool and windy weather even on sunny days. Occasionally, vehicles in the parking lot are broken into – leave valuables at home, lock them out of sight in the trunk, or carry them with you.
