The Colorado Thirteeners (13ers) are mountains between 13,000 and 13,999 feet in height. While the 14ers have become quite popular in recent years, there are over 700 13ers in Colorado; This site is dedicated to all of these great peaks.

If you’re looking for information about the 14ers, or content related to mountaineering in Colorado, please visit www.14ers.com. 14ers.com is loaded with photos and route descriptions for Colorado’s highest peaks.

I created these sites as a resource for people interested in Colorado’s peaks and they are not cluttered with advertisements. I hope you find the information useful.
