Emerald Pools is the hike almost everyone does and almost nobody looks up first, which is how people end up walking to a dry rock in August and wondering what the fuss was.
It is not one trail. It is three, stacked up the same hillside from the same trailhead, and picking the wrong one is the whole problem.
The three trails, and which one you actually want
The trailhead is across the road from the historic Zion Lodge, shuttle stop 5. Follow the sidewalk across the lodge lawn, cross at the crosswalk, and go over the bridge. The trail on the right is Lower; the trail on the left is Middle.
| One way | Climb | Surface | Who it is for | |
|---|---|---|---|---|
| Lower Emerald Pool | 0.6 mi | ~131 ft | Rough pavement, 96% concrete | Anyone. Small children, tired legs, an hour to spare |
| Middle Emerald Pools | 0.9 mi | ~333 ft | 80% firm soil, steep at the start | The view. Canyon open below you from a sandstone ledge |
| Upper Emerald Pool | +0.3 mi | +~76 ft | Stone steps, then soft sand | The quiet one, at the foot of the cliffs |
Those are the Park Service’s surveyed measurements (the Lower and Middle trails were assessed in March 2025). For the Middle route the park gives the round trip too: 2.2 miles out and back.
The three connect, and they also connect to the Kayenta Trail, which is how you reach the Upper Pool from the Grotto, stop 6 instead — two miles from that end.
The thing nobody tells you first
The waterfalls are seasonal. The Park Service’s own wording for the Lower Pool is “ephemeral waterfalls”, and for the Upper, “majestic, seasonal waterfalls.”
In spring, or within a day or two of rain, water comes off the ledge above the Lower Pool and the trail walks behind it. That is the photograph everyone has seen. In a dry August it can be a drip, and the Upper Pool a shallow green puddle at the base of a cliff.
This does not make it a bad walk — the Middle trail’s view is worth the climb in any month, and the pinyon-juniper shade is welcome when the canyon floor is over 100°F. But if the water is the reason you are going, check that it has rained before you build a morning around it.
You cannot get in the water
Not a suggestion. Swimming is not permitted, and the park asks visitors not to enter the pools at all: they are fragile, and they are an essential water source for the animals that live here.
There is a second reason. Zion has a standing advisory about toxic cyanobacteria in its water — the park’s guidance is not to submerge your head in or drink water from the streams anywhere in the park. Restrooms and water filling stations are at the Lodge, which is where to fill a bottle.
Dogs are not allowed on these trails, as on almost every trail in Zion.
When to go, and what it will be like
It is busy. It leaves from the Lodge, it needs no permit, and it is the obvious thing to do with a spare hour, so mid-morning in summer the Lower trail is a slow-moving line on a path that narrows to about two and a half feet in places.
The fix is the same as everywhere else in this canyon: go early, or go late. The first shuttle puts you at stop 5 before the canyon warms up, and the last two hours of light empty it out again.
In winter the Lower trail ices up — the park flags it specifically — and it is paved, which does not help. Microspikes are not a silly thing to have in the pack in January.
The edges
It is an easy trail with real drops next to it. The Middle route runs along a sandstone ledge above the Lower trail with nothing between you and the edge, and the park’s standing advice on this hike is short: avoid the cliff edges.
Nothing here requires scrambling and nothing here requires nerve. It is simply not a path to let a small child run ahead on, which is the one thing worth saying out loud about a hike this gentle.
The Park Service’s trail pages for the Lower, Middle and Upper trails carry the surveys in full. Figures checked 23 September 2026.
