Colorful cliffs that are a unique mix of dark columnar basalt, red sandstone, and buff colored limestone enclose the lush green of the oasis. The trail leads 4 miles to a large pool called Parson Springs where this considerable stream springs to the surface from the underground course it has followed through the majority of the canyon. Up canyon from this point surface flow only occurs during snowmelt and after summer monsoons. The limestone layer just above the streambed is riven with small caves. Flat ledges of red sandstone extend to the water's edge.
Songbirds flit through the tall cottonwoods and thick mesquite bosques.
At a number of points additional springs flow from the canyon walls through gardens of columbine and watercress. All these features combine to make this trail one of the most popular, and one of the most crowded, on the forest. If you visit this truly exceptional place please exercise extra discretion in making sure the impact you create is as slight as possible. No mechanized vehicles in Wilderness. No camping is permitted in this portion of the canyon.
