Mill Creek Canyon is a canyon in the Wasatch Mountains and part of Millcreek Township on the east side of the Salt Lake Valley, USA. It is a popular recreation area both in the summer and in the winter. It was named after all the mills that were once located in the densely forested canyon. It is home to two restaurants and six Boy Scout Day Camps.
Mill Creek Canyon is next to Parley's Canyon on the north and Big Cottonwood Canyon on the south. Though perhaps the most accessible canyon to Salt Lake City, its upper reaches are much less visited than neighboring canyons.
The upper trails in Mill Creek Canyon are open to biking on even-numbered days only.
