The Narrows information
The most famous backcountry route is the unforgettable Narrows , a 16-mile journey into skinny canyons along the Virgin River's north fork (June through October). Plan on getting wet: at least 50% of the hike is in the river.
The trip takes 12 hours; split it into two days, spending the night at one of the designated campsites you reserved or finish the hike in time to catch the last park shuttle. The trail ends among the throngs of day hikers on Riverside Walk at the north end of Zion Canyon. A trailhead shuttle is necessary for this and other one-way trips.
