Weeping Rock is another one of those things inside Zion that is easy enough to do, but oh so beautiful. It is only a half mile roundtrip. Although not very long or challenging, it is pretty steep so not really accessible with wheel chairs or strollers.
Begin at the Weeping Rock parking lot, then cross the stream on the footbridge. The trailhead breaks off to the left, opposite Hidden Canyon, East Rim and Observation Point Trailheads. If you visit when you come for the race, you can just drive private cars to the parking lot.
