Hidden falls is a beautiful little waterfall with minimal crowds. When I say minimal, I mean I've only seen another person there 1 of the 5 or 6 times that I have been. Take it in. Stay a while. Scramble around the small canyon for different perspectives of the falls or the creek. If you don't have a neutral density filter, the light in the evening is great for longer exposures.

Street parking on right hand side of s big cottonwood canyon rd. Also, a small parking lot off s big cottonwood canyon rd near trailhead to hidden falls
