Trails range from level, mowed paths through fields to steep, rocky trails deep in the forest.

The Ravine Trail winds through a hemlock forest overlooking a ravine and features rock stairways and stepping stones across a small stream.

The Lake Shore Trail features a 300-foot board­walk through a floodplain swamp and good views of Fields Pond and its 22-acre island.

The Beechwood Trail creates several longer hiking loop options around the sanctuary, connecting the waterfront and Lake Shore trail to the interior of the property. This heavily forested trail passes through a stand of American Beech trees.  Beechnuts are eaten by a variety of birds and mammals such as mice, squirrels, black bears, foxes, ruffed grouse, turkeys, blue jays, and nuthatches.

The Marsh Trail runs along the edge of the wetlands and pocket fields near the Nature Center.

The Fern Trail forms a loop with the Marsh Trail and Ravine Trail. It goes through a forested wetland, with a diversity of tree species. Raised bog bridging allows dry-footed access to this forested wetland.

The Brook Trail connects the Ravine Trail to the Lake Shore Trail. Follow the brook through mature forest and look for animal tracks along the way!


The sanctuary provides year-round habitat for wildlife ranging from small salamanders and tree frogs to more than 130 bird species, to bear, and even moose. In early spring, the center comes alive with the sounds of owls and frogs. Warblers, bluebirds, orioles, and tanagers are among the late spring and summer winged visitors. At least 20 varieties of butterflies have been recorded at the sanctuary, visiting feeders and the wildlife-friendly garden surrounding the Nature Center. In autumn, hawks soar over the fall foliage, and in winter, the sanctuary is crisscrossed with tracks of weasels, hares, fishers, fox, bobcats,and coyotes.


The land that is now Fields Pond Audubon Center was donated to Maine Audubon and the people of Maine in 1994 as a bequest from the estate of Katherine Curran to create a sanctuary for wildlife and people.  The Curran family kept cows, harvested ice from the pond in winter, and cut wood from the forest. Their gift of land included 1,600 feet of lakeshore, a stream and ravine, several wetlands, fields, forest, and a 22-acre island in Fields Pond.

In the winter of 1998, Maine Audubon opened the L. Robert Rolde Nature Center, named after the Bangor-born, nature-loving father of a lead donor. To create a “green” building, Maine Audubon staff and volunteers worked with the architects to reduce waste, conserve energy, reuse natural resources, and use products that don’t pollute the earth and atmosphere.
