There are many National parks around the border between Utah and Arizona. This “Grand Circle” area is the best place to visit in the U.S. for road tripping. But those National Parks are always popular therefore I recommend to visit those places before or after high season. You might spend an hour for just to get parking spot sometimes in high season. Bryce canyon is one of the popular National Park.
We got Bryce canyon NP in end of August. It was not very busy so we decided to hike “Navajo Trail”. Navajo Trail is popular short trail in Bryce canyon. I highly recommend to hike if you can have a time. It takes only an hour. But you can walk in between beautiful rocks. Also there is some natural bridges on the trail. You can’t enjoy these hidden natural sculpture from view point.
