Located in Willow River State Park near the Minnesota border, the Willow River descends 45 feet over the falls. The main drop is about 15 feet high but more than a hundred feet wide.
A sandstone gorge nestles the falls beneath 200-foot high walls. Geologists estimate the rock at the bottom of the gorge is about 600 million years old and have found trilobite fossils in it.
Here’s a brief video showing Willow Falls:
A great trail to see the terraces from is the Willow Falls Hill (Gray) Trail. It runs 0.85-miles round trip on Willow Falls State Park’s eastern side.
