Two separate but nearby North Andover parks, both overlooking lovely Lake Cochichewick. Osgood alone has 200 acres of land, and Weir adds 194 more, so there is lots of room to roam here.
Check the excellent website of the Friends of North Andover Trails for events at these places, and more information.
