We have done three major hikes and walked the rim during our stay. First, we hiked Navajo Loop to Queen's Garden and came up Wall Street. Bryce is not really a canyon, it is an amphitheater. You can look at it from the rim and it is beautiful. But hike down to the bottom--700 to 800 feet--and the experience is very different. Just remember, if you hike down 700 or 800 feet, you have to hike up the same amount. We have gotten lots of exercise!
