White Grass Ski Touring Center is a cross-country skiing facility located in Canaan Valley in Tucker County, West Virginia. It originally opened in 1979 on White Grass Knob near Harrisonburg, Virginia. Two years later, the operation was moved to the site of the second Weiss Knob Ski Area. The resort uses Weiss Knob's former lodge as its day lodge; it is one of the oldest dedicated cross country ski areas in the United States. Because of its status as a former downhill slope, White Grass is an unusually steep cross country area, with nearly 1,200 feet (370 m) of vertical rise—more than at neighboring downhill slope Canaan Valley Resort State Park. Its 45 trails are rated approximately 30% easy, 55% intermediate, 15% most difficult; climbs are available to the summit of 4,436-foot (1,352 m)
