Moss Glen Falls of Granville, Vermont offers two spectacular roadside waterfalls within the Granville Gulf Reservation. Moss Glen Falls isn’t the largest waterfall in the state. At 35 feet, the horsetail cascade along Deer Hollow Brook offers a quiet respite from the sometimes busy Vermont Route 100. (Well, as busy as Vermont’s roads can get, that is.) After a heavy rain, Little Moss Glen Falls, a thin horsetail 50-foot waterfall, is found closer towards the parking area.
