Kolob Arch is reached by a strenuous backcountry hike from Lee Pass in the Kolob Canyons section of Zion National Park. The route follows Timber and LaVerkin Creeks to a viewpoint of one of the world's longest freestanding natural arches.
The round trip is about 14 miles, so this is a deliberate hiking objective rather than a quick roadside stop. Check trail and permit conditions before setting out.
