Confirmed from Willow River State Park's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

🏞️ beautiful scenery 18 mentions

“Willow River State Park is a beautiful park filled with activities to do like hiking, swimming, fishing and sightseeing.”

Beautiful nature park, but I’m only giving it four instead of five stars for one reason. The large crowds at the Falls ruins the vibe and people crawling all over the falls, ruins the nature around the it. I think they should find a way to eliminate people from climbing and walking across the falls and river.

★★★★☆ — Jay , Feb 2026

Willow River State Park is one of those parks that feels way more dramatic than you’d expect for eastern Wisconsin. The main draw is the 45-foot Willow Falls – a wide cascade that looks great year-round, especially after rain or in early spring when the water’s high.

★★★★★ — Samuel , Jun 2026

This place is awesome. It has nice wide trails with some narrower hiking only winter trails. The waterfall was very cool as well as the story behind the former dam. I don't like the available PDF map with the trails but the gal in the office was very helpful.

★★★★★ — John , Dec 2025

Willow River State Park is a beautiful park filled with activities to do like hiking, swimming, fishing and sightseeing. Bring plenty of water as you will be walking a lot to get to places on the trails.

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.

“Downsides: bathrooms at the trailheads could use updating, and the park gets packed on Saturdays from May to September.”
