Dunn Falls

Before you go
Waterfalls are hazardous by nature — wet rock, cold water, and unstable edges — and flow varies enormously with season and recent rain. Trail figures here describe the route as documented, not conditions today. Check Appalachian National Scenic Trail (NPS) / Mahoosuc for closures and current conditions, and confirm land status before setting out.
Frequently Asked Questions
Dunn Falls drops about 80 feet. That makes it the 285th-tallest documented waterfall in this inventory, taller than roughly 62% of the falls listed here. Height comes from published land-manager and survey records, not from our own measurement.
The Dunn Falls Trail / Appalachian Trail spur (Dunn Notch) reaches it about 3.2 miles (out-and-back) with roughly 500 feet of elevation gain, rated moderate. The nearest town is Andover. That describes the route as documented, not conditions on the day — check with Appalachian National Scenic Trail (NPS) / Mahoosuc for closures and current conditions.
Late spring to fall (May-Oct). Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
