Kayaking the Narrows is only recommended for advanced paddlers. A backcountry permit is required for all boat use in the park.
Technical canyoneering and rock climbing are popular activities (for experienced individuals only). Route descriptions are available at the Backcountry Desk. First-timers should buy a dedicated guide book or hire a guide (see the What's Nearby section).
In 1918, the director of the National Park Service renamed Mukuntuweap National Park to Zion, making it easier to say and promote.
Red and tan Navajo Sandstone of Zion Canyon has been exposed by the work of the Virgin River, which transports millions of tons of sediment to the Colorado River each year.
The Virgin River drops 50 – 80 feet per mile, one of the steepest stream gradients in North America.
