The Moab area is one of the most amazing places. Drive into Arches national park (get there early and have your park pass already purchased). Put something inspiring on your stereo as you drive up the first hill...it will make your hair stand up when you take that first magic turn on the road. Get a reservation for Fiery Furnace guided trail (not that many slots per day, and you want to go early....it lives up to its name when the sandstone gets heated by the sun).
For a fun break, go into Sand Dune Arch (its one of the smallest arches in the park and seriously fun for a family). If you have never been to Arches, make sure you make the hike out to Delicate Arch for sunset. Go at least two hours before sunset and take a picnic. Its incredible to watch the sun go down and makes the hike even more worth it. Take a flashlight as you will be hiking back after the sun goes down (dont do the drive in overlook...its lame in comparison to actually standing at DA).
South of town, on BLM land, there is a large expanse of dunes and swales to play on. Its somewhat remote, but you can run and run (ATV/UTV) for hours. Make sure to take extra gas, you will use it (dont ask...I admit to nothing).
I have been to Moab every year for 40+ yrs (grew up in Utah). My favorite place on the planet....
