Rather than sitting in traffic on the way back from Salt Lake City we took a detour to Big Cottonwood Canyon for a short hike to Hidden Falls. The parking lot is located 4.4 miles up the canyon and is on the inside of a hairpin turn. It's easy to miss so pay attention when you get close. Once you park you actually have to cross the road to get to the trail. It sure would be nice if there was a crosswalk to at least indicate to the cars that people are crossing. Nothing. Be careful.
