The Gold Street Trail near Belchertown and Amherst Massachusetts is an easy 1.9 mile out-and-back hike through woods owned by UMass. Near the end of this GPS section of the trail is a building owned by Umass - you can turn around here for 1.9 miles total or continue on for another couple of miles.
The trail continues on for another 2 miles or so and hooks up to the radio tower on the Mount Lincoln Trail.
This property is owned by UMass but they allow hikers to walk the trails. Dogs and biking are allowed here, but do not park directly in front of the service gates - you will get towed.
