The Grand Circle Trailfest is a 3 day trail-running festival which takes place in the heart of North America's most scenic national parks:
Bryce Canyon, Zion, & Grand Canyon on October 13-15, 2016

 
 

Perhaps nowhere are the forces of natural erosion more tangible than at Bryce Canyon. Its wilderness of phantom-like rock spires, or hoodoos, attracts nearly two million visitors a year. On day one of the Trailfest, you'll see all of the beauty but avoid the crowds as you run on remote trails through the magical hoodoos unique to the Paunsaugunt Plateau.  

 

The towering sandstone walls and deep slot canyons of Zion National Park are unique to anywhere else on earth and attract 3 million visitors a year.  On day two, you'll run remote
trails along the edge of a mesa, offering you commanding views of the majestic sandstone towers that make Zion famous.

 

The Grand Canyon is one of the seven natural wonders of the world, and attracts 5 million visitors per year. On the final day of the Trailfest, you'll run along the remote North Rim of the canyon to several overlook points that few others will ever see!
