Tannery Falls is a waterfall on Grant Brook in Grafton County, New Hampshire, in the Northeastern Highlands region. It lies about 1 miles southeast of Lyme and roughly 65.5 miles northwest of Manchester as the crow flies.
Its height has not been recorded in the source data. By form it is a cascade, descending over a series of rock steps rather than in a single drop.
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.
