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.

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.

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
