Beaver Brook Cascades

Beaver Brook Cascades is a 80-foot tiered in New Hampshire, on Beaver Brook. The water falls in 12 distinct tiers.

It's fullest after rain, and flow can drop off during dry spells — plan around recent weather.

Plungeworthy rates Beaver Brook Cascades 8.6/10 — drop everything. The score weighs its scale, how confidently it's mapped, and its character.

Beaver Brook Cascades isn't one waterfall — it's roughly a thousand vertical feet of continuous cascades pouring off Mount Moosilauke's north side, no single drop bigger than about 50 feet, strung along 0.7 miles of the Appalachian Trail out of Kinsman Notch. Total-drop surveys range from about 790 to 1,200 feet depending on where you stop counting.

The trail that climbs beside them is one of the AT's legendary steep sections: wooden steps and metal rungs bolted to the rock by the Dartmouth Outing Club, gaining relentlessly with the water crashing beside you the whole way. The trailhead sign explicitly advises hikers lacking experience to take another trail — take that at face value.

The first cascade is an easy 0.3-mile walk, which makes a taste of it available to anyone; seeing the full chain means about 1.1 miles up the steepest sustained trail on this list.

Spring snowmelt is spectacular and also when the rock steps are most treacherous. Avoid in ice or heavy rain — the polished rock beside the cascades is unforgiving. Fall is the sweet spot: moderate flow, grippy rock, and color.
