Preston Falls Professional Guide
Detailed Trail Description from our Guidebook
"Although the big rocks and wild Tuolumne River scenery give a higher-country feel to this canyon, its low-altitude location welcomes hikers long after the real high country is under snow. This trail makes a pleasant day hike or off-season overnighter. Boulders litter the forest floor, so it seems only fair that a heavy growth of trees and shrubs has taken root in the crannies of the canyon walls. No glaciers buffed these walls to a monumental surface, as they did the rock walls of Hetch Hetchy, less than 12 miles up-canyon. Our trail follows the river, keeping a fairly even gradient, until we meet a mass of large granitic blocks that constrict the river in a narrow gorge. We climb over the rocks on the left, enjoying the view of the white cascade and green pools below. Less than a mile later we surmount a second rocky knoll, this time on a couple of scrubby switchbacks."
