Rocky Gorge, located just off the Kancamagus Highway in New Hampshire's White Mountains, is a powerful narrow gorge where water is almost always rushing through, even during droughts. Carved by glaciers, the Gorge is a breathtaking scenic area where water pours over the 15-foot falls with a deafening thunder. Water at the foot of the falls churns ferociously as it sends the Swift River on down its way. The footbridge over the gorge provides an excellent photo opportunity looking upstream to where the Swift River narrows as it cascades into the gorge.
