About this Location

Cascade Marsh is a New Hampshire Fish and Game Waterfowl Management Area, where hunting is permitted in season. The marsh is almost a mile long, and exploration by canoe or kayak from the launch area will open up areas not visible from the dam and Cotton Road viewing areas.

From the dam parking lot, a 0.1-mile walk past the gate will lead to some old gravel pits on the right.
