Max Delta Trail is a 2.7 mile trail within Phoenix, Arizona on the South Mountain Preserve. This is an out-and-back trail and it is considered beginner. 

The trail has a less than 300 feet elevation gain, so you don't have to huff and puff your way up the trail, but still offers nice views of the Phoenix Valley and Gila Crossing. 

What makes this trail unique is that it there was once a mine called the "Max Delta" mine, which, of course, is what the trail is named after. On the trail you can see foundations from structures that once stood on the mountain side, with an old brick fire place that remains standing today. 

The Max Delta Mine operated in the early 1900s, supplying massive amounts of Gold, Silver, and Copper. in 1935 Max Delta Mine was the fourth largest producer of gold in the US.Courtesy of placesthatwere.com

The mine is still accessible and has an extensive system of tunnels and train tracks. However, please be aware the hazards of exploring abandoned mines; there are risks of flooding, rusty nails, falling down large drops, and rock collapses. Use caution!

This hike is a cool exploration option, and offers a neat hands on look into the history of the Phoenix area.
