Trace the western shoreline of a Lake Cochichewick or enjoy an ascent through rare barrens habitat to scenic views of the Merrimack Valley.

The rewards of Weir Hill—pronounced “wire hill”—include a shimmering lake shoreline, an expansive panorama of the Merrimack Valley, and the diversity of ten different types of plant communities. Generations of agricultural use, a history of fire, and cutting and mowing regimes have created a patchwork landscape of a 60-acre oak-hickory forest to hillside seeps, intermittent streams, wet meadows, and other plant communities. Several threatened state-listed and watch-listed species—including  violet bush clover (Lespedeza violacea), and butternut trees (Juglans nigra)—are subtle signs of Weir Hill’s past that reveal themselves along the way.

Weir Hill, Osgood Hill, and the two-mile-long Lake Cochichewick are scenic, prominent features in the northeast part of North Andover. Great Pond Road was laid out on the east shore to take advantage of the views across the lake as well as the hills rising just beyond. Regional trail connections allow visitors to extend their trip with access to destinations north, west, and south of Weir Hill.

Follow the Edgewood Farm Trail to reach the meandering shore of Lake Cochichewick, which dominates the east and south edges of this reservation and provides memorable water-level views. Continue south on the yellow blazed Cochichewick, Alewife, and Stevens Trails to access the Pleasant Street parking area, Stevens Beach, and the Stevens to Stevens Trail or complete a full loop of the property to return to the Stevens Street parking lot.

Those seeking a more rigorous hike can follow the Weir Hill Trail (blue blazes) or Scrub Oak Trail (red blazes) to experience rare barrens habitat and enjoy hill top views of Lake Cochichewick and Mount Wachusett and Mount Monadnock to the west.

The Mills to Hills Trail leads west of Stevens Street, allowing access through wet meadows to reach Osgood Street. Beyond this point walkers can continue on this trail to reach the historic mills and downtown North Andover.

Property is open daily from dawn to dusk.

Free to all visitors.
