Things To Do

The geological features, within City of Rocks, are internationally renowned for rock climbing. The granite spires range in height from 30 to 600 feet. These spires, carved out of the landscape by wind, rain, and snow, feature textured rock that is tailor-made for climbing. City of Rocks offers a mixture of moderate and advanced climbs, often found side by side. Routes span a broad spectrum of features and challenges that require a full range of technique and style that are not generally found in one climbing area. About 700 routes have been developed to date. For information on climbing in the Reserve, climbing closures, and climbing guides, stop at the Visitor Center.

The climbing experience program offers visitors an introduction to the experience of climbing in a supervised setting.
