The trail distance between Mono Village to the summit is 5.5 miles.
From Mono Village trailhead, proceed south into the woods, after crossing Robinson Creek on a bridge. Take Horse Creek Trail (poorly signed, can be confusing) and follow it up the drainage of Horse Creek. After about 2 miles you reach the first meadow, where the official trail turns left heading out of the drainage. Now take a use trail on the right to follow the creek up-valley, passing a second meadow. In some places the maze of use trails can be confusing. At the third meadow above, head toward the lowest gap in the head of the valley, to the right of the black Horse Creek Peak. Scramble up talus piles until reaching Horse Creek Pass, passing it about 100 ft higher on the right side to avoid steep snow plugging the pass. South of the pass the terrain is gently rolling slabs.
After crossing Horse Creek Pass turn right toward Matterhorn Peak, ascend slabs and then sandy slopes until you reach several big rocky towers. After reaching the top of the East Couloir where you can look down on the glacier on your right, angle left (south side) for easier rock to the summit.
None for this route in summer.
