An unimpressive trailhead leads to a pretty canyon with nice water features and cascades. There is a waterfall we didn't see, as we stopped before the final stream crossing and the steep, faint path that leads up to it. I just didn't have enough energy left for that final push. Maybe we'll go back and see it some day.
We visited Adam's Canyon mainly because we're trying to check off as many of the 'medium' difficulty hikes as we can in our guide, 60 Hikes Within 60 Miles: Salt Lake City, before moving on to the 'difficult hikes'. We got a late start because Dixie had an interview in the morning and I ended up pushing myself a little harder than my body was willing to deal with which gave me some killer nausia . . . of course, the tomato and avocado sandwich I had for lunch wasn't exactly the perfect hiking fuel.
This would be a great fitness hike for locals (and we saw a lot of people on the trail doing just that), but I'm not sure it is worth the drive to the Kaysville area for us American Fork folks, unless I come back just to see that waterfall I missed.
