Emerald Pools is the Zion family hike — three tiers of waterfall pools cut into the sandstone above Zion Lodge, connected by a network of trails that lets parties pick a difficulty level and turn around when they're done. The Lower Pool is a paved walk; the Middle Pool requires actual climbing; the Upper Pool is the destination for the half-day version. Most first-time Zion visitors do at least the Lower Pool, and many do the full circuit.
What the pools are
The "pools" are catch-basins where the runoff from the higher slickrock pours over the sandstone cliffs and collects on intermediate ledges. The water comes from the high country above the canyon — Lady Mountain, Mount Majestic, the Three Patriarchs — and seeps through the porous Navajo sandstone to emerge as cliff springs above each pool. The "emerald" color is from algae blooming in the warm water in summer; in cooler months the pools read more brown than green.
Lower Pool
A 1.2-mile paved round trip from Zion Lodge across the river, around the base of the cliffs, and to the lower catch-basin. The trail is wheelchair-accessible (with assistance on the slope), works for strollers, and delivers the basic Emerald Pools experience without committing to the climb. The Lower Pool sits at the base of the cliff with seasonal waterfalls dropping from the Middle Pool above. In spring and after monsoon storms, the falls run hard; in late summer they thin to a trickle.
Middle Pool
The trail to the Middle Pool branches off the Lower Pool route and climbs roughly 200 feet across slickrock benches and dirt switchbacks. Round trip from the Lodge is 2 miles. The Middle Pool is a flat, shallow basin on a sandstone shelf above the Lower Pool's waterfall — you can walk to its edge and watch the water spilling over. The pool itself is not for swimming (NPS prohibits entering any of the pools), but the shelf is a comfortable spot to sit and have a snack with cliff-canyon views in three directions.
Upper Pool
The Upper Pool is another 0.5 miles of climbing from the Middle Pool, along a steeper trail that ends in a sandstone amphitheater at the head of the drainage. The Upper Pool is the largest of the three, set against a curved cliff with a tall thin waterfall coming in from above (in season). Round trip from the Lodge to the Upper Pool and back is about 3 miles with 350 feet of elevation gain. This is the most photographed of the three pools.
The closure history
The connector trail between the Middle and Lower pools was closed for several years following a 2019–2020 rockfall on the cliff above the Lower Pool. The closure rerouted parties wanting to do all three pools through a longer loop using the Kayenta Trail (which connects to the Grotto trailhead area). Some sections of the original loop have been reopened with reinforcement; verify current status with the NPS before relying on a specific route.
Don't enter the water
NPS rules: no wading, no swimming, no soap, no submerging. The pools are sensitive desert water sources and the hanging gardens and seep ecosystems around them are damaged easily. Rangers enforce this, and there's a visible difference between the pools at Zion and the typical "creek pool" elsewhere in the West because the no-entry rule is taken seriously here.
Where it fits
Emerald Pools is the Zion trail families do when Angels Landing is too much and the Narrows requires too much wading. The Lower Pool alone is a forty-five-minute round trip from the Lodge that delivers a real Zion experience to visitors with limited mobility, small children, or just an hour to spare. Most visitors who do the trail end up doing all three pools and treating it as their Zion half-day. One of three accessible Zion experiences alongside Pa'rus and the Riverside Walk.
