About two years ago, we did a whirlwind trip from SLC to Moab to St. George and back to SLC. We covered Arches, Canyonlands, Bryce and Zion. I joined my son and our new daughter in law, this was her first time going out west. Needless to say we were exhausted, but got to show the DIL a lot lot of Utah in a few few days. We rented side by sides and drove from downtown Moab (on the "city" streets) to Chicken Corners. If your Jeep is well equipped, I suppose you could do this ride. There were plenty of Jeeps and lesser vehicles on the trails, just not sure I would want to drive my "get around town" vehicle over jagged rocks, hairpin turns, bumps, etc. for hours.

I have also visited Antelope State Park (about an hour north of SLC) and Dead Horse State Park (about a half hour from Moab). Bother are definitely worth visiting. Only catch with Dead Horse you are not to drive in very early in the morning or late at night. However, I believe if you are a registered camper in the park you are allowed to drive there after dark (hint).

If you are into snow skiing, Snowbird will likely be at least partially open until late May. If your not into skiing, you may be able to take the tram to the top of the mountain (for a fee) for a visit, great views and a restaurant at the top (food was decent, nothing special).

Finally, I have visited Zion a few times over the years and never had the time to visit the other less popular side known as the Kolob Canyons until our most recent trip. I definitively recommend visiting this slightly off the beaten path part of the park.

I am by no means an expert on Utah, as most of our trips focused on skiing, with an occasional trip to southern Utah. Feel free to ask away, hopefully I can help.
