Superior Falls was a rare interstate waterfall as it was shared between the states of Wisconsin and Michigan since it flowed on the Montreal River, which defined the border between the states near the southern shores of Lake Superior. This turned out to be one of the easiest waterfalls for us to visit during our Great Lakes Trip because it was barely a couple minutes walk from the trailhead to the view you see pictured above. That said, we did notice trails going in opposite directions leading to the bottom and the top of the gorge so there was the option of extending a visit here. In any case, the main drop of the waterfall was said to be 60ft tall. Apparently, there were more tiers, but we didn't do them so we can't comment more. The trails and lookouts were all on the Michigan side. It didn't seem like the Wisconsin side was accessible.
When we first arrived at the trailhead (see directions below), we saw right away that there was hydroelectric infrastructure. That kind of dampened any desires that we had of extending the excursion beyond witnessing the main waterfall, as we were less inclined to stick around when the main attraction was more or less adversely impacted. That said, the power company running the hydro infrastructure here was said to be required to maintain a minimum flow rate (about 20 cubic feet per second). When we saw the waterfall, it seemed to have decent flow. I guess without this requirement, this waterfall could very well disappear completely (like so many other waterfalls sacrificed in the name of dams) so this was another one of those exercises in compromise between economic development and a healthy environment.
We visited Superior Falls as one of a handful of stops during the long drive between Duluth, Minnesota and Paulding, Michigan. The nearest town of any significant size was the dual towns of Hurley, Wisconsin and Ironwood, Michigan (separated by the Montreal River). From Ironwood, we would have to drive west on the Highway 2 for about 12 miles to the Hwy 122. Then, we would have to turn right to go north on Hwy 122 for about the next 5 miles, which would eventually cross back into Michigan. A signed turnoff for Superior Falls would be on the left, which then took us on a short unpaved road leading to a large clearing, which was the car park for the falls.
This drive took us around 25 minutes, but since our clocks were on Central Time, we actually lost an additional hour since Michigan observed Eastern Time.
Coming from the other direction in Ashland, Wisconsin, we would drive east on the Hwy 2 for 22 miles to the Hwy 122. We would then turn left to go north onto Hwy 122 and follow the directions as above.
For geographical context, Hurley, Wisconsin was 146 miles (under 3 hours drive) west of Marquette, Michigan, 225 miles (over 4 hours drive) northeast of Minneapolis, Minnesota, 263 miles (about 4.5 hours drive) north of Madison, Wisconsin, and 403 miles (about 6.5 hours drive) northwest of Chicago, Illinois.
You can use the form below, but if you find our host's interface too troublesome to use (especially if you're trying to upload photos), then just send a text submission anyways using the form, but also let us know that you'd like to attach photos. If you've provided an email address via the form, then we can reply back acknowledging your request, and you can then reply to that email with your photo attachments. We're very sorry about this, but there's not much we can do about SBI's terrible interface.
