Dunnings Spring Falls

Winneshiek County, Iowa — about 25 ft, shorter than most.

Dunnings Spring Falls tumbles down a limestone hillside in a spring-fed run at Dunning's Spring Park in Decorah. While local sources cite a 200-foot total run, the World Waterfall Database lists the visible drop at about 25 feet, reached by a short paved walk from the gravel lot.

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 City of Decorah Parks & Recreation for closures and current conditions, and confirm land status before setting out.

Spring and fall. Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
