Bryce Canyon National Park is one place that you need to see in person. The rock formations and hoodoos are awe inspiring with the way the sun hits them, especially in the evening. The Navajo trail takes you to the bottom of the canyon and back up in one big loop, just make sure you do not miss the signs or you may be in for a detour. If you can only do one thing while at the park, walking the Navajo trail would be my recommendation. If you have time, take a drive up to Sunrise, Sunset, Inspiration, and Bryce viewpoints. The sunsets are amazing up there! You don’t want to miss them.
