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.
