Taos Ski Valley, the granddaddy of all New Mexico skiing areas, opened in 1957. The resort has some of the most challenging slopes in the country with a majority of expert rated slopes. Hint: To get the most out of your skiing, be sure to pay attention to the signs at the base of each lift. They show the waiting waiting times at the other lifts.
Here is the Taos Ski Valley skiing site that has all of the information you need to have a fabulous time skiing and/or snowboarding at TSV. Casa-de-Toro is only 3.5 miles from the slopes.
