A pretty good trail for a long run. There are many intersecting trails, not always well marked, so you need to pay close attention to your route on the app as you go.Show more

This walk provides an outdoor museum of geologic features carved by the last glacier. It features a 40-foot-high ice-contact face, pitted by kettle-holes that were formed when sand and gravel settled around chunks of ice left behind by the glacier. Eskers also wind through the property alongside erratics, a drumlin, and a kame terrace. The Gray family created a pond by damming the stream that flows through the property to Hop Brook, a major tributary of the Sudbury River. Only the fireplace remains of the cabin the Grays built near the dam, once the site of skating parties and dances. Stone walls enclose their former garden on the south side of Hudson Road.
