The biggest thing around here is pay attention to rain in surrounding areas. People die every year at Zion from Flash flooding. Be aware and act accoringly and you'll be fine.

I would suggest using On-X off road to help you when your in the area.

We moved to the area two years ago and I learned much about the local trails and their difficulty level by watching "Matt's Off Road Recovery" channel on youtube, then researching the places he performs rescues.

My neighborhood borders Sand Hollow State Park, much of that is advanced off-roading. People get stuck in the sand there all the time.

All of Utah is beautiful, enjoy your trip!
