Trails at Broadmoor

Explore 8 miles of trails at Broadmoor Wildlife Sanctuary, including a 0.6 mile universally accessible All Persons Trail. The trails are easy to rugged and lead you through the shade of mature woodlands into open fields and along the edges of streams, ponds, and marshland. 

The trails are great pathways for birding, photography, and sketching. With the exception of the All Persons Trail, trails at Broadmoor have roots, rocks and rough terrain in some places.

Trail Descriptions

Mill Pond/Marsh Trail

Length: 0.4 miles

You might glimpse a mink or muskrat at the water’s edge or spot a Lady’s-slipper orchid on the forest floor in spring or summer. A spur trail to the right at signpost 3 leads to a rock outcrop and bench, a great place to view the marsh.  Mallards, Wood Ducks, Great Blue Herons, and Green Herons are often seen.

A spur trail to the right brings you to a field overlook with a 180 degree view of the fields and woods beyond. Nesting bluebirds, hunting foxes, and soaring red-tailed hawks might be seen in the open fields along this trail. Field sparrows and Indigo buntings may sing in nesting season. From signpost 7, go right along the Mill Lane and follow Old Orchard Trail along the edge of the woods with views of the fields looking north. At the end of the field Old Orchard Trail joins Quacking Frog Trail.

There are benches on either side of the platform. An audio tour accessible by cell phone interprets some of this walk during spring and fall. Learn more

Boundary Trail

Length: 0.5 miles

Details: From signpost 5 go left to cross over Indian Brook on an old cart road, continue to a sharp right turn through the woods with views of Wildlife Pond. Mature trees at the beginning sometimes attract Great Horned Owls in winter. The trail emerges from the woods with views of the field and Wildlife Pond beyond. This can be a good spot for birding the field edge and the pond. Look for great blue herons and wood ducks in the pond and northern cardinals, black-capped chickadees, white-breasted nuthatches, and the occasional northern mockingbird along the field edge. 

Charles River Trail

Length: 1-mile loop

Details: Cross South Street to walk through white pines then continue left or right at signpost 11 for a loop along the Charles River. The trail has varied topography and drops down to follow the river for nearly half a mile. Cardinal flower blooms along the edge in summer and tupelos turn a burgundy color in fall. In winter, mixed flocks of ducks and geese may be seen. Away from the river, the trail continues through dry upland oak and pine forest where eastern towhees, wood thrushes, and eastern wood peewees may be heard in spring.

Glacial Hill Trail

There is a rocky stretch of the trail just before signpost 16 the start of a 0.6 mile loop over a dry sandy ridge where shadbush blooms.

The loop trail takes you up to an overlook with a bench to observe the pond from above. Continue along the pond edge and look for ospreys, ring-necked ducks, red-tailed hawks, and pileated woodpeckers. In spring, listen for Virginia rails. A small area of northern bog can be found on the northern edge including sundews, pitcher plants, larch, red spruce, swamp milkweed, and poison sumac, but this area is only accessible by boat.
