Great Falls Reservoir sits just off the Appalachian Trail near Falls Village, Connecticut, offering a worthwhile detour for thru-hikers or section hikers passing through town. Formed by a dam on the Housatonic River, the reservoir spills into Great Falls—a wide, powerful cascade that’s especially impressive after heavy rain. While the AT doesn’t pass directly by the falls, it’s less than half a mile from the road walk into Falls Village, making it an easy side trip. The area has historical significance as a former mill site, with old stone structures still visible near the river. For hikers stopping in town, Great Falls adds a dose of natural drama to this otherwise mellow stretch of trail.
