There's a ton of paper in this book, overboard, in my opinion. Wading through the pages in search of a hike is downright laborious. I've taken quite a few of the Sierra hikes and the information hasn't been detailed enough to really give me a feel for what to expect on the trail. They miscalculated the mileage and sometimes the elevation. I think it would be a better book if they chopped out half of the listings and concentrated on the truly best hikes in California.
