Tonto Natural Bridge is tucked away in a tiny valley surrounded by a forest of pine trees.
Tonto Natural Bridge State Park has been in the making for thousands of years. It is believed to be the largest natural travertine bridge in the world. The bridge stands 183 feet high over a 400 foot long tunnel that measures 150 feet at it widest point. You can see the Natural Bridge from four different parking lot level viewpoints without hiking down to the bottom; however I would recommend the moderately strenuous Pine Creek Trail, which takes you along the creek area to the Natural Bridge.
This is a wonderful place to hike in for the day if you are camping in nearby in the area near Payson.
It would also be a good full day activity if you are driving up from the valley. Allow at least two hours to drive to the park entrance, and depending on the ability levels of your hikers, you could spend from an hour to several hours, exploring all the hiking trails and lookout points.
There are picnic areas available, first come, first served, with restrooms.
