I did several hikes in the Bighorn Mountains recently, including 3-day and 1-day hikes in the Cloud Mountain Wilderness. I used this book to pick which hikes to go on, and got average results. There are several reasons (1) the Cloud Mountain Wilderness is part of Bighorn National Forest, but the book doesn't list any of the hikes in the rest of the national forest (why not?) (2) it gives poor maps (3) it gives poor descriptions of what to expect of the scenery (4) The author does not appear to be a local (why not?), but rather a travel writer of some sort.
I would give it a 3 star rating if it had the other lackings but listed other Bighorn national forest hikes (even only the good ones), but, as it was, this was ridiculous. It needs a major overhaul. On the other hand, it gets 2 stars rather than 1 star because it is the only thing out there, and I give the author credit for leading the way. A tip - if you buy the book, you won't want it once you're done with it - leave it at the trailhead in the registration boxes for the next person to come along.
