About this spot
Middle Falls is the ~25-40 foot middle drop of the Purgatory Brook falls system on the Lyndeborough/Mont Vernon line, NH, dropping into a shaded rock amphitheater; the area was a popular summer resort destination a century ago (dance hall, bowling alley, camping). Pin matches the OSM-confirmed location exactly. Sources note swimming is generally discouraged here due to slippery rocks, strong currents in high flow, and sudden depth changes; the documented swim spot on this brook is Lower Falls downstream, not this tier.
Safety first. Cliff jumping is inherently dangerous and can cause serious injury or death. Conditions — water depth, submerged hazards, and access — change constantly. CliffScout is community-sourced reference information, not a guarantee a spot is safe. Always assess the conditions yourself before jumping, and never jump where you're unsure. You assume all risk.
