How to make the most out of it?
Well, looking at the Zion National Park website, I realized that there is a company that offers horseback rides. They do it for all 3 parks (Grand Canyon, Zion, or Bryce Canyon).
We already have a trip to the Grand Canyon Planned, and the Bryce Canyon shortest ride is 2hrs.
The Zion shortest ride is 1hr
The Zion ride costs $40+tax per person and no previous experience is necessary.
