Surrounded on three sides by the river, this restored grassland field is accessible by either foot or boat.

Charles River Peninsula plays an important role in protecting the beauty and environmental value of the upper Charles River corridor. Where the Charles River makes a nearly 180-degree twist in the valley, a wooded shoreline of birch, hemlock, and beech conceals an upland peninsula that rises gently to a 20-acre open field, which was farmed for more than a century.

Follow a narrow footpath that tracks the river along the reservation’s shoreline, and head to the field’s highest point for views of the Charles River. An old wooden railroad trestle is visible at the western end of the reservation.

The AllTrails website has a description and map of a hike at the Charles River Peninsula.
