Tonto Natural Bridge Warm Spring Professional Review and Guide
"A warm spring with a large volume of water. The water flows out of a hillside, through a meadow, and eventually forms a dramatic waterfall. A small spring with a large flow of water comes out of the hillside within the Tonto Natural Bridge State Park and flows downhill through the meadow and over a cliff. The water forms a small creek with small pools at the bottom of the cliff. The spring water is used for various purposes, but nowhere is there a place to bathe in it. Instead, there is a small trail that leads down the cliff to a better view of the natural bridge.
Although there are no bathing opportunities at this spring, it provides one of the geological wonders of the state. The Tonto Natural Bridge Warm Spring helped to form the immense travertine structure for which the state park is named. One of the nation’s largest travertine structures, the natural bridge was formed in part by the precipitate of this spring. The cliff and bridge themselves are sights to behold, and make for a pleasant day trip. The spring has been diverted through the meadow, but otherwise is in its natural state. The location is in a developed state park, with a visitor center, picnic tables, and hiking trails."
