This gallery shows images from a hike up Mount Aire trail in Mill Creek Canyon in the Wasatch Mountains just east of Salt Lake City. This is a great hike for fitness freaks. The Forest Service says the trails is 1.8 miles and gains 1821 feet. So that would be a thousand foot gain in elevation per mile.
This hike shares the trail head with the Elbow Fork Trail and provides spectacular views of Mill Creek Canyon and Parleys Canyon.
