Avalanche Falls
A 45-foot cascade where Flume Brook enters the head of the narrow granite Flume Gorge in Franconia Notch State Park. It is reached as the climax of the ticketed Flume Gorge boardwalk loop, not as a free roadside 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 Franconia Notch State Park for closures and current conditions, and confirm land status before setting out.
Frequently Asked Questions
Avalanche Falls drops about 45 feet. That makes it the 456th-tallest documented waterfall in this inventory, taller than roughly 34% of the falls listed here. Height comes from published land-manager and survey records, not from our own measurement.
The Flume Gorge Loop (boardwalk and stairs) reaches it about 2 miles (loop), rated easy. The nearest town is Lincoln. That describes the route as documented, not conditions on the day — check with Franconia Notch State Park for closures and current conditions.
Late spring to fall (paid loop typically open 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.
