Leadville was one of the world's great mining camps. Incredible wealth was generated in this two-mile-high city from gold, lead, silver, and zinc mining and smelting. 'Everyone' came to Leadville, including Presidents Grant and Theodore Roosevelt. Houdini, Oscar Wilde, Buffalo Bill Cody, and the Ziegfield Follies performed at the Tabor Opera House which still has tours of this 1879 structure. Institutions such as the Guggenheims, the May Company, Marshall Fields, and Dow Jones, got their start in Leadville. Musical productions The Ballad of Baby Doe and the Unsinkable Mollie Brown were based on Leadville residents. The world's largest molybdenum deposit is still being mined nearby.

Leadville's scenic beauty is unparalled. It lies in the Rio Grande Rift between two spectacular mountain ranges, the Sawatch and Mosquito. The two highest peaks in the entire Rocky Mountain chain are displayed prominantly across the Arkansas River Valley from town, Mount Elbert (14,440) and Mount Massive (14,421). In the fall, the golden aspen abound as a reminder of Leadville's golden days. Leadville can be accessed from three directions by the Top of the Rockies Scenic and Historic Byway. Incredible scenery abounds along any of these highways. Leadville is an affordable, central spot to headquarter in, with easy day trips to Vail, Aspen, Breckenridge, Fairplay, and Salida and a plethora of recreational activities.
