There are 6 Trans-Sierra highways of which only three are all season roads. Stanislaus Peak is a symmetrically round, flat topped peak located near Sonora Pass on California State Route 108, one of the Trans-Sierra routes that is closed during the winter. There are a couple of 11,000 ft. peaks in the area that can be summited in a day or less with Leavitt Peak to the south the highest. Stanislaus is a red colored ancient volcanic cone located north of Sonora Pass in the Carson - Iceberg Wilderness and is a sharp landmark for those traveling the Pacific Crest Trail. The summit is very flat and covered with flat rocks that reminds one of roof tiles both by look and the clinky sound they make as you walk on them. This is an easy class 2 non-technical climb that can be combined with Sonora Peak to the south for a nice day of hiking. Do not be surprised by men in uniform. This area is used by the United States Marine Corps for mountain warfare training. The main base is about 10 miles east of Sonora Pass on State Route 108. From Stanislaus Peak one can see Round Top and Highland Peak to the north, Leavitt Peak and the Emigrant Wilderness to the south, and the Dardanelle Cones to the west.

Getting There

The main trail head is located at the St. Mary Pass parking area on the north side of the road 0.5 mile west of the Sonora Pass summit. It is located approximately 60 miles east of Sonora, CA along California State Route 108.

Red Tape

There are no permits required for day hiking in the Carson - Iceberg Wilderness or for parking at the trailhead. If one is camping, a Wilderness Permit is needed. An online permit form for a Wilderness Permit is a available. Permits can also be obtained from any Stanislaus National Forest Ranger Office including the Mi Wok and Summit offices located along CA State Route 108 . Only one permit is needed for continuous trips passing through more than one wilderness area. If you plan on using a stove, even if on a day hike, a fire permit is required and can be picked up at any U.S. Forest Service office.The fire permit is good for the entire state of California.

When To Climb

The best time to climb is June (if the snow is not too deep) through October . State Route 108 is closed 7 miles east of Strawberry from the first significant snowfall in the fall to a spring opening. Memorial Day weekend is the usual target date for opening the pass. Some years it is earlier and some years later. The summit log had entries as late as the first part of November and as early as middle May.


Camping is allowed in the Carson - Iceberg Wilderness with the proper permit. Use a bear proof canister in the back country. To the west of the summit are several Forest Service campgrounds that have free camping. The catch is there is no water available, so bring plenty. Down from the pass in both directions are regular Forest Service fee campgrounds. The closest being Kennedy Meadows to the west and Leavitt Meadows to the east. There is also a store and restaurant fairly close to the west of the pass at Kennedy Meadows and at Dardanelles.

"An expedition under Gabriel Moraga discovered the river in October 1806 and name it Rio de Nuestra Senora de Guadalupe. (Arch. MSB, vol. 4, Munoz, Oct. 2, 1806.) It was on this river, the next day, that they found the rancheria of the 'Taulamne' Indians, but the name 'Tuolumne' wound up on the next river south.

Estanislao was an Indian, born at Mission San Jose, baptised, and given a saint's name -- probably for one of the two Polish saints called Saint Stanislas. Estanislao ran away from the mission -- inducing some other converted Indians to leave with him -- and became a rebel. The Mexicans, under Gen. Vallejo, defeated Estanislao in two battles in May and June of 1829. (Gudde, Place Names, 320; Historic Spots, 368, 539.) The river later became known as Rio Estanislao, and was anglicized into 'Stanislaus River' by Fremont in 1844. (Fremont, Expeditions, 359.)

The peak was named in the middle 1870s. In 1877 Lt. Macomb climbed it and found 'a fine monument erected by a reconnaisance party of the Coast Survey.' (Wheeler Survey, Report, May 1, 1878, 143.) The name is on atlas sheet 56D, 1878-79. Thus, by a series of unlikely events, the name of a Polish saint was given to a mountain in Apline County, California."

Slight correction -- St Mary's pass parking is 0.8 miles from the summit (not 0.5 miles) and is south of the road (not north). The trailhead is north of the road.

Re: Parking

I've always parked north of the road. I was up there Labor Day weekend and parked north of the road along with 4 other cars.

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.
