Visitors to Zion National Park can now borrow an all-terrain wheelchair to better explore the area. Zion is the first national park to own and maintain such equipment, which expands park access to those with disabilities, mobility issues and injuries. The Extreme Motus wheelchairs glide over rocks, sand, gravel and grass and can float on water. They can be checked out on a first-come, first-served basis, and Zion plans to offer additional wheelchairs and accessibility devices in the future.
