The Upper Emerald Pool Trail in Zion National Park has a lot to offer for being one of the shorter hikes in the park! This trail starts at the Virgin River bottom with views up and down Zion Main Canyon, then turns and continues up Heaps Canyon and affords views of hidden water falls and sheer Navajo Sandstone Cliffs. These water falls are all runoff fed, so depending on the amount of rain/snow fall, the waterfalls can be a gushing flow, slow and steady, or nothing but a drip. That said, there is typically enough flow during the year that each of the three pools along this trail has some water in it. In just a few hundred feet of elevation gain, the vegetation changes from cottonwoods to pines, and spotting local wildlife is common along this trail. Many travelers take a picnic with them to eat at the top of the trail as they enjoy the view of the Upper Pool and waterfall. This trail is a must on your next trip to Zion!
