When the autumn temperatures drop and there's suddenly snow on the peaks, aficionados of the steeps at Taos Ski Valley turn their attention to the Millenium Pass.

Until October 1, Taos regulars can get their season pass for $575—a savings of over 40 percent on the $999 full rate. The only caveats to the Millenium Pass is pass holders can't ride the lifts during the post-Christmas week holiday, and the number of days on the hill is limited to 70 for each pass holder.

As a bonus, every purchaser of a Taos Ski Valley Millenium Pass gets three free days at Telluride and Durango Mountain Resort, and discounts on tickets at Monarch Mountain, Crested Butte, Jackson Hole and Kirkwood. Days at other resorts don't count against days on the Millenium Pass.

You can purchase your Millenium Pass at the Taos ticket office on the bottom floor of the base area from 9 a.m. to 4 p.m., or by visiting www.isalessite.com/skitaos.

One new twist to the Taos Ski Valley calendar is that the mountain will only be open Thursdays through Sundays from opening day on Thanksgiving, November 24, through Sunday, December 11. The lifts will start turning every day on December 15.
