From I-89 exit 10 in Sutton, go north to the T intersection of Shaker and North Roads (visible from the end of the exit ramp). Turn right onto North Road and go 0.4 miles. At Kearsarge Valley Road, turn left and go 1.6 miles. At Baker Road (dirt road), turn left and go 1.2 miles. Immediately after crossing a brook, turn left and go .1 mile to the parking area, where there is a dam with a view of the marsh.
There is a good view of the south end of the marsh on Cotton Road. Return to Baker Road, turn right, and go 0.4 miles, turn right and go 0.25 miles to a parking area next to a bridge.
Pied-billed Grebe, American Bittern, Great Blue Heron, Hooded Merganser, Belted Kingfisher, Common Yellowthroat, and Swamp Sparrow are commonly seen in summer in and around the marsh.
During migration, several species of waterfowl stopover. Many passerines and a few shorebirds can also be seen, especially around the old gravel pits near the dam.
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.
