Close

Bear Brook begins at the outlet of Hall Mountain Marsh near the four-corner intersection of the towns of Allenstown, Deerfield, Candia, and Hooksett. The brook descends to the north, through Deerfield, then turns west and reenters Allenstown. Nearing Deerfield Road, the brook is impounded by Catamount Pond, with a state park beach and picnic area. The brook flows northwest from the pond and reaches the Suncook River in less than a mile.
