Bryce Canyon is a relatively small national park in southwest Utah. The elevation is high with most of the park at the 7,000 to 8,500 feet level. I have visited Bryce a couple of times in May. It can be quite warm during the day and still turn VERY chilly in the late afternoon.
The rock formations here are much different than those found in most of the parks in southern Utah and Arizona. Cedar Breaks is similar but you cannot hike down into Cedar Breaks whereas there are many trails where you can hike down among the "hoodoos" of Bryce. Most of my photos were taken from the Queen's Garden Trail.
