Adam's Canyon is about half an hour north of Salt Lake City, it is an out-and-back hike to a waterfall. The trail is steep the whole way, the first part is up a sandy hill with switchbacks and no shade. There are also some places near the beginning where the trail splits and it is hard to tell which way goes to the falls. When in doubt take the trail to the right that is going up the hill.
Since the trail is so steep, it takes longer than you would expect given that it is less than 2 miles to the falls. I started thinking I was almost there when there was still about a quarter of the hike left.
After the long, hot hike up (it was 103 degrees the day I went) the falling water created a welcome cooling breeze.
