The Pigeon River forms a portion of the border between Minnesota and Ontario. On the Minnesota side, you can visit Grand Portage State Park. The most popular (understandably) waterfall in Grand Portage State Park is the High Falls of the Pigeon River, which are very impressive. They are also easy to visit!
There are a number of other waterfalls on the Pigeon River, though, that don’t get nearly as much attention. If on the Minnesota side, it’s again understandable. One of the falls, Partridge Falls, is not necessarily easy to access because of rough road. Middle Falls, where there seems to be two different portions, can be accessed from the park entrance, though it requires a 1.6 mile hike one-way. This hike is by no means on flat ground, and it is steep at points, though by no means terrible. There is no simple boardwalk to the falls, though! Once you get there, you may be slightly disappointed, since High Falls is so much taller and more impressive. I would say the solitude you will experience at the Middle Falls would be a positive, but it was pretty quiet at the High Falls when I visited in mid-May.
As a side note, if you go to the Ontario side of the river, you will likely have a much easier time visiting these falls. From the Minnesota side, you can actually see the road that hugs the river, leading almost directly to the falls. So if you don’t want a workout, I would suggest that.
Directions (from Minnesota)
1) Head north on MN-61 from Grand Portage to the entrance of Grand Portage State Park. You’ll see the border gate as you’re turning in.
2) From the parking area, start along the trail toward High Falls. You should be heading west.
3) Instead of heading toward High Falls, continue along the Middle Falls Trail. It is at least 1.6 miles one-way. Near the end of the trail, the trail splits (and creates a circle). The left fork in the trail leads you to the falls quicker, and I would even return from that direction. The right fork, adds a longer distance, and didn’t hold any interest for me.
Directions (from Ontario)
1) On ON-61, find Route 593. Head west on Route 593, where after about 1 mile (maybe even less), you’ll pass a parking area on your LEFT. It’s really the only parking area, so turn in. If you’re unsure, there’s a sign in the parking area to indicate your near the falls.
2) Walk along the old road upstream to the falls.
Accessibility: 3/10 (from Minnesota), 9/10 (from Ontario)

Update: Alright, so I had a chance to visit Lower Middle Falls when I was in the Thunder Bay area in late April 2012, and I can tell you, that for the most part, it is much easier to visit the Ontario side of the falls. The only difficulty is a minor one…There is no large sign indicating that you’re passing the parking area for the falls. I ended up passing the parking area, and turned around because I felt I had gone too far. I was correct in my hunch, as the parking area I saw was for the much shorter hike to the falls. On the Minnesota side, it’s a 3+ mile hike one-way…In Ontario, it’s about a 1/4 of a mile. I also feel the views are somewhat better on the Ontario side. For a while, I wasn’t even sure I was looking at the same waterfall.
