The wild and scenic corridor of the Merrimack River cuts through the land here just as it did two hundred years ago. Located in the state capital, the 136-acre Sewalls Falls Recreation Area provides trails and river access. The north end of the area has a boat launch ramp; at the south end, a small park sits among the remains of an old power generating facility. May/June and October/November are prime months for Atlantic brood stock salmon fishing (raised at the US Fish and Wildlife Service’s Nashua Hatchery), fishing license and salmon permit required. Download a helpful fishing map. This recreation area has a seasonal restroom.

Great blue herons and ospreys feed here. A walk along the river’s edge reveals many of the secrets of this special place. Be on the lookout for spotted sandpipers, tree and bank swallows, and belted kingfishers; watch for evidence of minks, otters, and raccoons. This section of the river provides important habitat for Atlantic salmon and freshwater mussels.
