Question: Which state park near Payson features what is believed to be the world’s largest natural travertine bridge?

Answer: Tonto Natural Bridge State Park, home to a 183-foot-high travertine bridge spanning a 400-foot-long tunnel that stretches 150 feet wide at its widest point. Travertine bridges are natural rock arches that form when mineral-rich water leaves behind layers of rock, and water flowing underneath slowly erodes part of the structure.
