Breckenridge was a gold camp before it was a ski town, and it never quite stopped acting like one. Prospectors founded it in November 1859, and the town was briefly spelled with an i to flatter a vice president and win a post office. It got the post office, the first between the Continental Divide and Salt Lake, then changed the spelling back in 1861 when that vice president joined the Confederacy. A hundred years later, in December 1961, someone cut ski trails on Peak 8, and the mountain has been growing across the Tenmile Range ever since. Today the old miners' streets sit at the bottom of five peaks, and Main Street really is lined with the clapboard and log buildings you see in the photographs.
The skiing is a different thing from Vail's. Where Vail is wide, Breckenridge is high: the town is at 9,600 feet, the Imperial SuperChair tops out at 12,840, and the bowls above it are steep, rocky and often windy. It is also a mountain of two halves, because Peaks 7, 8 and 9 are mostly intermediate and learning terrain, and the hard stuff is on the upper reaches of Peak 8, Peak 6 and the chutes. Five days is the right length because four days cover the five peaks without rushing, and the fifth gives your legs and your lungs a day off while you learn how the town got here.
The plan runs Monday to Friday: Peak 9 and Peak 8 on Monday, Peaks 7 and 6 on Tuesday, the high-alpine Peak 8 on Wednesday, Peak 10 and the Peak 9 chutes on Thursday, and a day of museums, Frisco and the lake on Friday, then you drive out on Saturday morning. Start on a Monday, in January or early March if you can, so that all four ski days are midweek and the museums are open on your day off. The first day stays low on purpose, because of the altitude.
