The North Fork of the Virgin River (aka "The Zion Narrows") is probably one of the most legendary canyons to hike in all of Zion National Park. The Zion Narrows is the section of the Virgin River just upstream from the Temple of Sinawava (the end of the road up the main canyon). Here, the majestic walls of the main canyon close in to form a tall and narrow canyon with beautiful dark corners and the Virgin River flowing around you. With beautiful flowing water and barely any direct sunlight reaching the bottom, this is the slot canyon that all other slot canyons are compared to.
