Sofar, this little baby is a favorite of my husband :).
The descriptions are very good, as well as the hike challenge. It even tells you how much water to bring. The trail maps are iffy, and my version was printed before the raise in entrance fees.
One thing that I can see missing in the legend of each trail is whether dogs are allowed. I have to research every trail we consider for this. But then I do recommend going online and researching anyways, as well as downloading a current trail map. I do like the GPS coordinates listed.
