A pretty brook that crosses under the Bruce Freeman Rail Trail. Keep an eye out for small wildlife near the water, and larger animals like hawks and foxes that might hunt them.

This section of the Mass Central Rail Trail (MCRT) runs for three miles through Weston, and is part of a planned 25-mile trail stretching from Berlin to Waltham. The trail is accessible from Church Street, Town House Road, and Concord Road, here. The trail is a multi-use path that allows bicycles, joggers, walkers, dogs, and horseback riders. Dogs must be leashed on the trail, and all users should yield to horses. Unfortunately there are no garbage cans along the trail, so users should take their trash with them to help keep this great recreational resource clean.
