Ok...
Follow up to my other question. What is the easiest, to hardest BWCA foot trails to follow? (Some of these trails I hadn't even heard of but found them on the Recreation.gov from BWCA permits)

Sioux Hustler Trail
Angleworm Trail
Snowbank Trail, Disappointment Loop,
Kek,
BRT
Pow Wow
Brule Lake Trail
Eagle Mountain Trail
Partridge Lake Trail
Big Moose Lake
Blandin
Herriman
Norway

I have only fully hiked a handful of these, so I will list the trails I have done. Take my response with a grain of salt. In order of difficulty navigating/following the trail from easiest to hardest:

1) Kek (to Disappointment trail intersection) - easy to follow, only difficulty in this section was making sure not to take a wrong turn on another trail (Snowbank, Disappointment, Benezie-Becoosin, other spurs)
2) Angleworm - one or two minor difficult spots, otherwise easy to follow
3) Disappointment - cleared last fall and I hiked it this spring, only got turned around once when I went down a campsite spur, tread not as well-developed as first two trails
4) Snowbank - a few spurs trails to look out for, some sections where cairns aren't immediately obvious, one r two other minor tricky spots
5) Sioux Hustler - a couple tricky sections where tread dies out, lots of following cairns, tricky stream crossing in high water

YMMV

Pow Wow is going to be the hardest, hands down, right now. If you don't know, a large portion of it burnt in the Pagami Creek fire back in 2011. The trail is slowly getting cleared and opened, but where the regrowth is happening the trail is pretty overgrown making navigation tricky.

The difficulty hiking the BW, other than 2 steps up-2 steps down for days, is finding your way around streams and beaver dams. Vegetation is unusually high and the trail changes relatively often. Get yourself a dog and train it to stay on the trail.

I've only done a handful of these. The problem with ranking "easiest to hardest" is that there are different things that make them easier or harder for different people, at different times, and in different ways.

On our trail clear invitations we set out to describe trips as easier or harder, but realized it's a trap to ever use the word "easy" for a wilderness trail experience. The trail can be totally flat, wide, and well signed, but become difficult in an instant due to weather, an event, or a mistake. So we started describing what about a given trip would be expected to introduce difficulty, with a general disclaimer about the inherent unpredictability of wilderness travel.

So with that said, here's my take on the ones I've done (or partially done):

Angleworm - it's short, which makes it "easy". It also gets a fair amount of day use. The trail is kind of tough, in that it has some significant elevation changes in short spaces, with some scrambling; it also has a long beaver dam crossing. The southeastern quadrant of the loop can be a little difficult for trailfinding, especially going north (counter-clockwise).

Pow Wow - this was a very popular trail before the Pagami Creek fire of 2011, because it's so "easy". Almost the whole southern stretch is on an old forest road so it's relatively flat and has a firm tread. The fire rendered it impassible for several years, but the whole trail is marked and only a few miles of it involve significant obstacles right now. Still, it's probably the "hardest" right now because of all the climbovers, and wayfinding can be tricky. Also, the first couple miles have substantial beaver activity, which makes it wet. You're extremely unlikely to see anybody else unless you're there when we're out clearing the trail.

Kek - I've only done the western half. That stretch is pretty "easy" in that there are relatively few dramatic elevation changes. I found wayfinding to be incredibly easy. There are some tricky beaver dam crossings, a terrifying single-log "bridge" over a waterfall, and wet patches, but generally it's in good shape, easy to follow, and not much harder than the Superior Hiking Trail. The spur trails off it can be a good bit more difficult, in terms of both wayfinding and terrain.

Sioux Hustler - I've only done some of this one, quite a while ago. I recall the trail being pretty easy to follow, but overgrown and very wet. More physically challenging than the Kek or Pow Wow, but no harder than Angleworm, which is to say, not bad for somebody who's in reasonably good shape. But I don't recall the specifics too well. I guess it's time to redo this one!

I have three. A Jack Russell Terrier, a German Shorthair Pointer, and a Cane Corso/Italian Mastiff... soooo.... ????

When I say easiest to hardest... I mean, easiest to follow, vs. hardest to follow. I don't care how challenging it is elevation wise etc.. just how easy it is compared to the Superior Hiking Trail which is SUPER easy to follow.

Wow yeah, I way overinterpreted your query, sorry.

Haven't been on the Pow Wow since before the Pagami Creek Fire, but have to agree with Minnesotian. A fire seems to really obscure any tread. All the downed trees, and then the heavy regrowth. Even logging activity (like was done at some point on the non-BWCA spur to the Sioux-Hustler) can make it hard to find trail. Next to those, trail in beaver meadows can grow in fairly quickly. I don't find trail across rock to be too bad, especially with the occasional cairn. I do wonder what the trails are like in fall and winter... have only hiked there in summer. Some of them must have some nice color in the fall, for sure.

Oh my... I can't believe you'd hike the BW in the summer. Between the bugs and the heat, I thought I was about to die the one time I tried it. I've hiked shirtless on the Pow Wow, but trust me, not in the summer. A nice indian summer day in October... Color can range from so-so to amazing. Hiking in 30-60 degree bug free weather is great. Sleeping in 10-40 degree weather, not so much, but equipment has improved considerably since I hiked the Pow Wow in early October 1989. On that trip, which resulted in failure because I tried hiking it counter clockwise and missed the Pose Lake turnoff (saw it, thought it was used by Moose Hunters). Coldest night I've spent backpacking was that trip at the Isabella River site and it got down to 10 degrees. But loved it so much, I returned a year later and completed the trail. Haven't done it since the fire and would love to do it again...

One could also argue that the trails are easier to navigate and follow in the spring and fall (especially the less used ones) because there is less brush to hide the tread. I hiked the Moss Lake trail last weekend as part of a loop with the BRT and CRT, and portions of it were brush higher than my head. "following" the trail was more about finding the past of least resistance than it was staying on the tread. That would be much less of an issue in the shoulder seasons.

Yeah, I would for SURE be hiking these in shoulder seasons.
