Red Rock Canyon Open Space (Colorado Springs, Colorado). Red Rock Canyon was an active quarry from the 1870s until the early 1900s...supplying stone for businesses and homes in Colorado Springs. As of 2003, the quarry has been an open space and a popular hiking, biking, and rock climbing destination in the Pikes Peak Region. I highly recommend doing all three activities!💯 For the moment, let's focus on hiking. You have the ability to hike as little or as much as you'd like at RRCOS. Connecting
