The Emerald Pools Trail is a mix between an easy and moderate level hike and is split into two parts.
The Lower Emerald Pools Trail is the easier part of the trail. It is mostly all flat, and 1.2 miles roundtrip. To get to the trailhead, you have to get off at Stop 5, Zion Lodge. When I visited, this trail was closed due to rockfall. Luckily, there are two trails to get to the Upper Emerald Pools Trail.
The Kayenta Trail is the alternative route to the Upper Pools. This trail is a slightly higher level, and is moderately difficult. The elevation is still low, around 200 ft. and it is about 2 miles long roundtrip. This trailhead can be reached from Stop 6, the Grotto.
The Upper Emerald Pools Trail is also a moderate level. It also has around 200 ft in elevation gain, and is around a mile long. The entire trip, taking either the Kayenta or Lower Pools Trail, would probably take around 2 hours, be 3 miles roundtrip, and go up in elevation around 500 ft.
Every trail is Zion is beautiful, but most come at the cost of large crowds. Hidden Canyon was one of the few that was not swarming with people, even in the late afternoon.
Roundtrip it is only 2.5 miles and can take around 3 hours. The elevation gain is much lower than some of the other challenging hikes in Zion, only around 850 ft. This is a harder hike, and at some points can be dangerous.
Camping in Zion is a must if you plan to hit all the cool trails! Staying just one day is definitely not enough.
Although there are several options for camping/backpacking in Zion, we decided to stay at the South Campground. Not only is it really conveniently located, but we also didn't have a reservation, so all we had to do was pack up our stuff and drive down!
