Welcome to "Bicycling Colorado's Mountain Passes". I would like to introduce you to Colorado's Mountain Passes, paved roads, trails, tracks and dirtroads that cross Colorado's divides. The following tables can be used to access pages about passes, with emphasis on information useful to cyclists.

The tables currently contain 102 recognized passes, and an additional 15 unrecognized summits, such as the road over Grand Mesa for example.

The pass pages are in two distinct formats. A few pages contain elevation profiles, maps, route suggestions, approach descriptions, a historical overview and pictures. The group of pages that are available in a detailed format changes from time to time. They are listed in

The longer format pass pages, along with those in a shorter format, can also be accessed through the following tables.

recognized Colorado passes	(-alphabetical order)
unrecognized Colorado summits	(-alphabetical order)
paved road passes/summits	(-highest elevation first)
unpaved MTB passes/summits	(-highest elevation first)

Passes/Summits by map location
north western Colorado	north central mountains	north eastern mountains
south western Colorado	south central mountains	south eastern mountains

Please note that there are some dead links in the individual pass pages referencing other passes, since this is not a completed product. But the tables should not contain dead links.

Additionally, there are sections covering other areas. See the links at the top of the white area.

as well as an introduction, describing what you can expect to find here in a little more detail.
