We planned riding separate ATVs, but after the test run, we decided to switch to 2 UTVs. We were glad we did. We did a UTV ride up by Bryce Canyon, and this one was more technical with some steep hills, sharp turns, bumps, & rocks. No problem with a UTV, but wouldn't have been as enjoyable for us on individual ATVs. (We are all around 60) Loved the stop & guide's information at the Indian fortress.
