Funny you should ask......we are leaving this month to head out to southern Utah with our UTV. Its our first time out with the UTV. Been thru the area about 3 years ago but just drove thru. My wife bought a great book on Amazon listing many of the ATV/UTV/Jeep trails with descriptions, mile markers, degree of difficulty, nearby CGs etc, etc, etc. It looks like it will come in very handy for the trip. The book was written by a guy who ran the trails and then critiqued them. Its broken up into 4 areas(north,south, east, west) around Moab.
