Bryce Canyon National Park in Utah is a popular tourist destination that's in some ways like a very small version of the Grand Canyon. It consists of a rim at between about 8000' to 9000' in elevation with the canyon itself a garden of "hoodoos", multi-colored limestone spires. Unlike the GC, the canyon is only about a thousand feet deep. Hiking below the rim is allowed, but due to the elevation and the gain some of those are considered strenuous.
