A Steep Beauty Water Canyon is a wonderful half-day hike, located an hour south of Zion in the Canaan Mountain Wilderness. Named for its year-round water supply via a number of reliable springs, the Water Canyon Trail follows Water Creek up and into a lush finger canyon, arriving at some nice, deep narrows. From there, the trail climbs up, up, up along rocky and sandy shelves on the canyon's western wall, gaining increasingly beautiful vistas.
Most folks who reach the top of the trail stop there, but those eager who have more juice in their legs can work their way north up dry washes to White Domes, where you can see over Canaan Mountain and into Zion Canyon.
Canyoneer's note: This is a description for the hike up the side of the Water Canyon. Water Canyon's watercourse may also be descended directly, using ropes, technical equipment, and canyoneering techniques.
