Bucket list your heart out
Yes, you could drive to all 5 Utah national parks in one day. But you shouldn't. What hike should you take your 6-year-old on when you're blissing out in Zion? Where should you camp in Moabduring the busy summer months? Can you go to Goblin Valley and the San Rafael Swell in the same day? How do you see Delicate Arch, Deadhorse State Park, and Canyonlands all in one weekend?
