Land around both East Branch and West Branch is posted against trespass. Some boaters on the East Branch have encountered a gun toting land owner with an ATV who has been known to escort groups until they are beyond his property.
As a result, access is often via carrying/dragging up a good trail (starting about a quarter mile the other side of the river/bridge from the wayside/parking on Hwy.61). It is a long, sometimes strenuous hike, but once you see the river, you'll realize why most think it's worth it.
When doing this trail, put-in above a great sliding, twisting drop where the Superior Hiking Trail (SHT) used to cross the river. That footbridge was washed out in a flood, but the bridge footings are still evident, and a sign directs hikers to a new footbridge a half mile upstream. (Spring of 2001, that was also swept off its footings. How many rebuilds until they figure a way that periodic flooding does not rip it out?)
The run has an amazing assortment of big sliding drops. All are runnable (at favorable levels) by boaters with confidence and skill. Most are surprisingly forgiving, in spite of their impressive size.
The final drop is probably of the most concern. A steep, broken slide leads to a wall of rock which diverts the river ninety-degrees left, through a somewhat narrow slot, to spill across shallow splines of rock and large boulder rubble before the calmer water below. The usual route slides down the right, into the 'elbow', then slides along the right-side rock wall (avoiding potential piton rocks to the left in the final chute), then rock-dodging through the pool below.
Downstream from here there is barely more than riffles, rips, and shoals, so fish (and people fishing) tend to congregate below this drop.
