Starting from the River Road parking area the Appalachian Trail (AT) passes through the open Ottauquechee River floodplain across 900 feet of boardwalk built by the Green Mountain Club. The trail then ascends to the falls viewing platform via an accessible switchback and spur trail built by the Vermont Youth Conservation Corps. From here, the AT continues its ascent through northern hardwood forest to Thundering Brook Road where a small parking lot can be found.
Thundering Falls provides the first universally accessible portion of the Appalachian Trail in Vermont with wheelchair-accessible parking on River Road in Killington.
