Despite receiving about 17 inches of rain and 90 inches of snow a year, much of Bryce Canyon has sparse vegetation except in the valleys. The contrarian is Swamp Canyon. A pair of creeks and a natural spring help to create a lush environment encircled by colorful plateaus and accented with dramatic buttes. For a closer look at this more intimate amphitheater, follow the 4.3 mile Swamp Canyon Trail. The two hour walk is rated as a moderate hike.
