The Merrimack River Trail is a 3.5-mile loop that follows the river and passes through wooded areas, wetlands, and fields. The trail is suitable for hiking, biking, and cross-country skiing, and is accessible year-round. The boat launch provides access to the Merrimack River, which is popular for fishing, kayaking, and canoeing. The launch has ample parking and a picnic area with tables and grills. 

The Merrimack River is a 117-mile-long river in the northeastern United States. It rises at the confluence of the Pemigewasset and Winnipesaukee rivers in Franklin, New Hampshire, flows southward into Massachusetts, and then flows northeast until it empties into the Atlantic Ocean at Newburyport. From the point where the Merrimack turns northeast in Lowell, Massachusetts onward, the Massachusetts–New Hampshire border is roughly calculated as the line three miles north of the river.
