In winter, visitors can ski at Mount Shasta Board & Ski Park, 104 Siskiyou Ave., Mount Shasta (800/SKI-SHASTA or 530/926-8610; www.skipark.com), which has 31 runs with 80% snowmaking, three triple chairlifts, and a surface lift. Lift tickets are $39. The Nordic ski center has 16 miles of groomed trails, and Terrain Park is geared toward snowboarders. The Learning Center offers instruction for adults and children. In summer you can ride the chairlifts to scenic views, mountain-bike down the trails (an all-day pass is about $15), or practice on the two-story climbing wall. Access to the park is 10 miles east of Mount Shasta (the town) on Highway 89.
