The Breithorn is a mountain in the Pennine Alps, located close to the Matterhorn. It is considered the most easily climbed 4,000 m Alpine peak. This is due to the Klein Matterhorn cable car which takes climbers to over 3,820 m (12,700 ft) for a starting point. The standard route (SSW flank) continues over a glacial plateau before climbing to the summit on a 35 degree snow slope. However, inexperienced mountaineers may run into severe difficulty if caution is not taken near cornices or in bad weather. For experienced climbers wanting more of a challenge, the half traverse of the Breithorn crest is another option. The Breithorn was first climbed in 1813 by Henry Maynard (climber), Joseph-Marie Couttet, Jean Gras, Jean-Baptiste Erin and Jean-Jacques Erin.
