In the winter months, Sun Valley becomes "Nordic Town, USA." The cross-country skiing is so good that the Norwegian Olympic Nordic Team treks to the Wood River Valley to train. The Annual Sun Valley Nordic Festival celebrates the area's 200 kilometers of groomed trails, the Boulder Mountain Tour Nordic race and the exceptional scenery for nine days, Jan. 30-Feb. 8.
New this year is the Snowball Special fat-tire bike race. The race is on Saturday, Jan. 31 and courses include a 20-kilometer loop, a 40-kilometer loop and a 40-kilometer relay on the White Clouds and Boundary Creek trails.
