“This park is way better than any video game,” says 13-year-old Alex Schaefer as he clambers up the base of Double Arch, one of more than 2,000 sandstone arch formations that form the filigreed lanscape of Arches National Park. “I really like that I can get so close to—and even sit under—many of the arches. And the sandstone rock is so smooth and curvy that it makes climbing super fun.”
