Begin hiking uphill and north from the trailhead. Soon you cross the highway and continue on up through forested switchbacks. Take your time at this elevation. The Dog Lake route continues straight ahead over the top of the ridge, while you'll go left along the ridge, still going uphill until the trail puts you onto the granite shoulder of Lembert. A bit of easy walking then a somewhat exposed class 2 hop puts you on top of the viewing platform for Tuolumne Meadows. Wind, sun and a lot of rock await you. The gentle Tuolumne River winds below, and you can see its source in the Lyell Glacier miles to the south.
Retrace your steps to descend, or go a bit further to Dog Lake, or circle around Dog Dome to come back to level ground to the west.
