South Brook Falls is a 51-foot waterfall on South Brook in Franklin County, Maine, in the Northeastern Highlands region. It lies about 10 miles north of Kingfield and roughly 99.9 miles north of Portland as the crow flies.
At 51 feet it is taller than the typical Maine waterfall of about 29 feet, ranking 25th of 80 with a recorded height. By form it is a horsetail, where the water keeps some contact with the bedrock as it falls.
The Northeastern Highlands are the mountains of northern New England and the Adirondacks, with spruce-fir on the summits and northern hardwood forest of maple, beech and birch below, and countless lakes and boulder-strewn brooks. Fast mountain streams drop over granite and gneiss ledges in chains of falls and pools.
