At Swift River Reservation, the East Branch of the Swift River, the largest tributary of the Quabbin Reservoir, links three unique, exploration-friendly tracts of land. Varied topography and flora support an abundance of wildlife, including deer, beaver, raccoon, porcupine, bear, bobcat, and coyote as well as numerous songbirds, owls, and birds of prey. With majestic old pine and hemlock lining its banks, Swift River is one of the most scenic streams in the Commonwealth.
