Echo Lake is a 38.2-acre (15.5 ha) water body located in Franconia Notch in the White Mountains of New Hampshire, at the foot of Cannon Mountain. The lake is in the Connecticut River watershed, near the height of land in Franconia Notch; water from the lake's outlet flows north via Lafayette Brook to the Gale River, then the Ammonoosuc River, and finally the Connecticut River to Long Island Sound, an arm of the Atlantic Ocean.
Echo Lake lies in Franconia Notch State Park. The park's Cannon Mountain ski slopes rise directly to the southwest of the lake. Interstate 93 (the Franconia Notch Parkway) runs along the lake's eastern shore, and New Hampshire Route 18 passes the lake's northern shore, where a state park swimming beach is located. Artists Bluff, a hill with open ledges, rises north of the lake and provides views south over the lake into the center of Franconia Notch.
