Over the course of 13 million years, the Virgin River has carved through the red sandstones of Zion National Park to create some of the most unforgettable scenery in the National Park System. In fact, this very act of natural erosion is responsible for "The Narrows," which is one of the premiere hiking adventures in the United States, possibly the world.
Despite the obvious evidence of the erosive force of the river, the river itself winds peacefully through the canyon. Natural river processes proceed unimpeded, allowing for seasonal flooding and meander migration, vegetative recruitment, and plant succession.
All watercraft use in the park requires a wilderness permit. For boating below the Temple of Sinawava, these permits are free and can be obtained at the Zion Canyon Visitor Center the day of your trip.
Permits to float the Virgin River are issued when the river is flowing in excess of 150 cubic feet per second. The US Geological Survey measures Virgin River flow rates. Watercraft must be specifically designed for whitewater use. Operators must be equipped with approved personal flotation devices.
