Grandeur PeakGrandeur Peak is an mountain summit in the Wasatch Range in Salt Lake County, Utah, United States.DescriptionGrandeur Peak is located southeast of downtown Salt Lake City on land managed by Uinta-Wasatch-Cache National Foreste. The peak is part of the Wasatch Range, which is a subset of the Rocky Mountains. Precipitation runoff from the mountain's north slope drains to Parleys Creek, whereas the south slope drains to Mill Creek. Topographic relief is significant as the summit rises above Parleys Canyon in 1.25 mile and above Millcreek Canyon in one mile. The peak is prominent on the Wasatch skyline, and it is the most accessible as well as easiest climb of the major peaks rising above the Salt Lake Valley. Reaching the top involves 3.4 miles of trail hiking with 2,300 feet of elevation gain, and the summit provides excellent views of Salt Lake City. This mountain's toponym has been officially adopted by the United States Board on Geographic Names.
