A one-mile, paved trail links Sunrise and Sunset points, and follows the rim of the Bryce Amphitheater. Along its path, there are numerous benches where you can stop and soak up vistas of the hoodoos below. Along the rim itself, limber pine trees, their roots often exposed, show how the land here continues to erode. The roots of these trees, some of them hundreds of years old, used to be below ground. Scientists estimate the rim of Bryce is eroding at a rate of two to four feet every century.
