Englemann Canyon (also spelled Engleman's Canon)[1][2] is a valley along Ruxton Creek, in Manitou Springs, El Paso County, Colorado.

The Civil War veteran and later inventor of the Simmons mattress decided that the canyon was suited for construction of a cog railway.

[10] Sights in the canyon include Artist's Glen, Minnehaha Falls, Son-of-a-Gun Hill, Hells Gate, the site of Halfway House, and Ruxton Park.

[14] In 1891, the canyon was described in The Illustrated American as "a narrow valley, with a steep mountain rising on either side, and the clear, sparkling Ruxton Creek rushing parallel to the track, sometimes dashing over rocks hundreds of feet below the train, and sometimes pausing for a moment to form a deep, smooth pool, such as the speckled trout loves to haunt.

[16][17] The stone hydroelectric plant generates electricity as Ruxton Creek flows into Manitou Springs from the mountain.
