This trail begins from the Lembert Dome/Glen Aulin Trailhead in Tuolumne Meadows. Walk toward the restrooms in the parking area to find the trailhead. You'll see the dome looming above the parking area to the east, although the aspect in view is not what you'll be climbing. The trail you'll take is signed for Dog Lake and Lembert Dome.
Begin hiking northeastward from the trailhead. Shortly the trail splits from the route to Dog Lake. Follow the right fork at this split. From this fork the trail begins to ascend more steeply. A rocky surface can make this route difficult on the return. The trail winds around the northern side of the dome where the trail fades and you begin climbing up the granite northeastern slope. This slope is gradual and nothing like the sheer cliff wall of the western side of the dome. Look for the summit and find your way toward it. The summit lies at 9,450 feet providing a view of the meadows below and the mountain ranges surrounding them.
On the return follow the same route. Be careful not to take the wrong trail as this area is highly impacted and trails abound. Leaving the granite slope turn left and descend westward then southward.
Directions from Arch Rock Entrance: Drive northward into the park toward the Yosemite Valley. Turn left on to Big Oak Flat Road and travel almost 9.5 miles to Tioga Road.

Walk east from the parking area to the trailhead, which is behind the restrooms.
