For those of you visiting Tonto National Monument, the Roosevelt Dam and Inspiration point are only a ten-minute drive away. If you enjoy viewing feats of engineering, the history of the Theodore Roosevelt era, or you just want to see the beautiful area from a different perspective, why not give it a try? At the time it was built it was the world's tallest masonry dam. It was since covered over in concrete, but if the lake is low enough you can still see some of the masonry. You can also get some nice views of the lake and there's a pretty interesting bridge (Arizona's longest two-lane inverted arch suspension bridge, which I sadly can't find my photographs of) to behold, right behind the dam.
There are few services at Tonto National Monument. A picnic area is near the visitor center, but no food can be purchased in the park. The tiny village of Roosevelt is 8 miles away. There is one restaurant there, but on the day of our visit it was closed, without explanation. The next closest facilities are at Globe, about 35 miles to the southeast, and Payson, 50 miles to the north.
Camping is not permitted in the park. However campsites are available nearby at Theodore Roosevelt Lake. I would recommend not only that you bring your own food, but also carry drinking water, be sure your tank has plenty of gas and be prepared for other emergencies that may happen in a remote area.
