This is the waterfall falling into the lower emerald pool in the Zion National Park. Following the trail you are passing behind the waterfall which is quite interesting when lot of water is carried. There are three pools, the lower, middle and the upper emerald pool. The trail can be walked as a round trip choosing a different path from the middle pool. Transportation inside the park is only possible with shuttle busses, so it is anyway regardless where you start and end the trail.
