More than 30,000 people crowded to Zion National Park in a single day over Memorial Day weekend as the iconic red-rock landscape at the already crowded park remains highly popular.
Some visitors waited an hour and a half to ride the shuttle in the popular park. Visitation Zion has spiked by 60 percent increase over the last decade, and most people crowd to Zion Canyon, a 6-mile corridor along the Virgin River.
Arches and Canyonlands also drew big holiday-weekend crowds. Superintendent Kate Cannon says the steady surge in visitors is hard on national resources as well as staffers and tourists.
