Awesome trail through a unique forest for this area. Saw lots of moose scat and a few grizzly tracks, but the only mammal we encountered was a doe. We were able to gather some mushrooms for dinner on one of our days, and found some good blueberry patches too!
If you're unfamiliar with this trail, as our group was, make sure to take the first logging road veering right after the trailhead/parking area. We ended up on an old, very abandoned "trail" that was not actually the trail when we started. Luckily we made it onto the real trail, but just be aware.
