Moab is a pretty epic place when it comes to wheeling...
If you have a little bit of free time, try and catch word of whats doing over at area BFE.
Thats the competition area, which if you're new to rock-crawling, will really blow you away.
If no one's running over there, probably not worth the trip. But if you can find out either by word of mouth, or meeting up with people on the trails that some people are running at BFE... it's worth spending a 1/2 day out there if you have time in your schedule.
Upper Helldorado isnt to hard to get to, and the waterfall there is notorious. Pretty cool to watch rigs try and make it... As well as run the comp lines.
Any way you slice it, there's tons of great wheeling to be had out there.
