Upper Emerald Pools

(1.0 mile / 1.6 km round-trip). Trailhead is across the highway from the Zion Lodge, via the Lower Emerald Pool trail. A moderately difficult trail to the upper pool. Swimming, wading, or bathing is prohibited in all four Emerald Pools due to dangerous bacteria in the water and in order to protect the aquatic wildlife and preserve this fragile area. Beware of steep cliffs; there has been at least one death from falling at one of the pools.
