Manitou Incline, Rail trail in Manitou Springs, Colorado, US.

The Manitou Incline is a hiking trail on the east slope of Mount Manitou, part of the Rocky Mountain flank of Pikes Peak above Manitou Springs, Colorado. It follows the washed-out bed of a 3 ft narrow gauge funicular built in 1907, climbing 2,011 feet over 0.88 miles on wooden steps, with a grade averaging 45% and reaching 68%.

Built in 1907 under Dr. Newton N. Brumback as a funicular to carry water and materials to tanks above Manitou Springs, the line later served tourists under the Pikes Peak Cog Railway. A 1990 rock slide washed out the rail bed, and the Cog Railway chose not to repair it. Congress formally abandoned the railway right-of-way in January 2013, clearing the way for the trail.

The name Incline comes from the straight, steep route of the former funicular, which carried water and materials to tanks on Mount Manitou from 1907. Today the Colorado Springs area's runners, soldiers from nearby bases and athletes from the US Olympic Training Center use the steps for timed workouts, and the top step is numbered 2768.

A reservation system limits daily visitor numbers, and booking should be made several days ahead. The descent follows the Barr Trail, a longer but gentler path that ends east of the starting point.

The steepest sections reach a grade of sixty-eight percent, making this one of the most demanding ascents in North America. Some steps are so high and narrow that hikers use their hands for balance.
