A view of Lower Bell Canyon Reservoir in the Fall. Bell Canyon sits just to the south of Little Cottonwood Canyon, in the Wasatch Mountains of northern Utah. The reservoir itself sits in the foothills above the city of Sandy, one of many communities in the Salt Lake Valley. The hike to the reservoir is a fairly short and enjoyable one, while more extended hikes can be had to Bell Canyon Falls, and Upper Bell Canyon Reservoir farther up the canyon.
