The three-mile Heron Marsh Trail takes visitors through prime wildlife viewing areas. The path includes a variety of Adirondack habitats, including wetlands, hardwood forest, and mixed conifer-hardwood forest. The trail begins near the deck of the Paul Smiths VIC Building. The first part of the trail takes you down near Heron Marsh, with two viewing platforms and an elevated tower to observe marsh regulars, including Great Blue Heron and American Bittern. The trail continues around Heron Marsh, passing the Shingle Mill Falls dam, then passes through a typical Adirondack forest community of mixed conifers and hardwoods, leading to a 900-foot boardwalk across Heron Marsh and Barnum Brook. The path then winds upward through a hardwood forest. The walking is easy with a few small hills.

The Heron Marsh Trail provides opportunities to study a variety of plants which flourish in different Adirondack habitats. The marsh itself hosts a number of wetland plants which grow in the Adirondacks.  These include floating plants, such as Yellow Pond Lily and White Water-lily.   Both of these plants are anchored to the bottom by roots and have long stalks to leaves that float on the surface of the water.  At lower water depths, emergents (such as Pickerelweed and Cattail) flourish. Bladderworts also thrive in the marsh near the trail; these are submersed free-floating plants featuring tiny bladders attached to the leaves, which trap and digest very tiny animals. Blue Flag Iris also grows in profusion in the shallow water of the margins of Heron Marsh. The upland portions of the trail feature wildflowers which thrive in typical Adirondack mixed hardwood-conifer forests, including Goldthread, Canada Mayflower, and Shinleaf. A wide variety of fungi also thrive along the trail, making it an ideal spot to study mushrooms.

Flowering shrubs and wildflowers seen on the Heron Marsh Trail include:

Sheep Laurel Goldthread
Spreading Dogbane Pipsissewa
Shinleaf Wintergreen
Blue Flag Iris Marsh Cinquefoil
Bunchberry Canada Mayflower
Clintonia Common Wood Sorrel
Painted Trillium Partridgeberry
Pickerelweed Pipsissewa
Shinleaf Starflower
White Water-lily Wild Sarsaparilla
Wintergreen Dewdrop (False Violet)
Indian Pipe Pickerel Weed
Hobblebush Cow-wheat
Spotted Touch-Me-Not Yellow Pond Lily
Trailing Arbutus Dwarf Ginseng
Carolina Spring Beauty Steeplebush
Leatherleaf Hop Clover
Helleborine Orchid St. John's Wort


Many species of birds can also be seen or heard from the Heron Marsh Trail.  Several different species of ducks nest on Heron Marsh, including Ring-necked Duck, American Black Duck, Common Merganser, Wood Duck, and Mallard. Red-winged Blackbirds are commonly seen perching on snags and shrubs on the marsh.  Swamp Sparrows nest among the cattails and shrubs along the margins of the marsh.  American Bittern often forage for food in the wetland vegetation along the edges of the water.  Great Blue Heron can also be seen on the edges of the water or overflying the marsh.  The transitional areas around Heron Marsh and the upland portions of the trail are home to a wide variety of birds, such as the Common Yellowthroat and the Black-capped Chickadee.

Birds which can be seen or heard on the Heron Marsh Trail include:

Cedar Waxwing Broad-winged Hawk
Red-eyed Vireo Nashville Warbler

The Heron Marsh Trail also provides an opportunity to observe some of the animals that make the VIC their home. There are two beaver lodges on Heron Marsh: one on the north side of the marsh and one on the south side of the marsh. Beaver activity is evident all around Heron Marsh. North American River Otters and muskrats can be seen throughout the yea, playing or feeding on the fresh-water mussels and clams in the marsh. The best time to catch sight of an otter is early morning or late afternoon. Two very common Adirondack rodents -- the Red Squirrel and the Chipmunk -- are frequently observed here. White-tailed deer are also occasionally seen along the path; in some cases, they have been observed wading on the edges of Heron Marsh. Snapping turtles make their home in the marsh; and painted turtles are often seen sunning on floating logs in the open water areas.

In winter, the Heron Marsh Trail becomes a classic cross country ski trail. Follow the light gray trail markers.
