About Onion Falls
Onion Falls is a tucked-away cascade in Michigan’s Upper Peninsula, set within the Ontonagon land unit of the Michigan Wild and Scenic River (WSR) system and managed by the U.S. Forest Service. The falls sit along a small forest stream on land owned by DESG, offering a quiet, secluded experience that changes with the seasons — spring runoff brings the most dramatic flow while late summer can be much gentler. The setting feels remote despite a relatively short approach: dense mixed forest and fern-carpeted slopes frame the plunge, making this a peaceful stop for hikers who enjoy off-the-beaten-path scenery. Because the site is overseen by the USFS, visitors should follow Leave No Trace principles and be prepared for variable trail conditions, especially after rain.
The Setting
Onion Falls sits at 1,099 feet within Ontonagon, Michigan Wild and Scenic River, in the foothills of Michigan.
Trail & Hike Details
Trail Description
The available management data do not list a specific USFS trail name or number, nor do they specify formal surface, grade, or trail class; in practice the path winds through forest, can be narrow in places, and tends to be uneven and muddy after wet weather. Hikers can expect a steady but not overly steep climb—good footwear and traction are recommended for the short descent to the falls and the return climb.
What to Expect
Visitors can expect a peaceful and quiet setting with a small but picturesque waterfall. The flow of the falls may vary depending on recent rainfall or snowmelt. Wildlife sightings are possible in the surrounding forest.
Accessibility
The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.

How we calculate this
This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.

Winter safety. Frozen falls are the one waterfall trip with a documented injury pattern: falling ice, and ice-glazed rock and trail. Wear microspikes, keep well back from the base and from overhangs, and never walk out on ice over moving water.

Weather Forecast
The Terrain, Seen by LiDAR
Aircraft-mounted lasers measured this ground to within inches. Trees and buildings are digitally stripped away, leaving the bare shape of the land the water has carved.
Through the falls the surface drops roughly 176 feet over a short, steep run of tiers. Elevation at the pin is about 1,127 feet.
Steep ground runs through the entire stretch: about 70 feet of descent in the 500 feet above the pin and 78 feet in the 500 feet below it. Facing south, the falls sit in full sun for most of the day, best photographed early or late.
