Climax is an extinct mining company town, railroad station, and post office located in Lake County, Colorado, United States.

[2] The town site is located at an elevation of 11,342 feet (3,457 m) at Fremont Pass on the Continental Divide of the Americas.

Climax is also a destination for automobile tourists, bicyclists, and photographers, but lacking commercial enterprise, the location is not well advertised.

[10][11] The high elevation means that Climax has consistently cold temperatures throughout the year, with frosts possible in any month and 53.5 mornings falling to or below 0 °F or −17.8 °C.

The high altitude, however, limits extreme minima as in the coldest weather Climax may be warmer than lower valleys; the record low being −33 °F (−36.1 °C) on January 12, 1963, and December 23, 1990.
