9/23/2017(am) • Zion National Park   
• A 45 minute drive from the highway to get to the North Rim
Probably the busiest NP I've ever been to.  Fortunately Dad and I got here early and took the shuttle up the Virgin River Gorge without a whole lot of waiting.  BUT, when we were done and ready to move to the next location within the park, we got on the shuttle to go back to our car and there had to be at least 1,000 people waiting for the shuttle.  When we got to the east side of the park, to the next location I wanted to go to, there was no parking for that spot within a mile in either direction.  I'm thinking I like the reservation system.
