Kirkwood is great for side country and just powder. Never too crowded because it's not close to other resorts, 2 parks, one for beginners one with big jumps. Many many tree runs and bowls. Slow old chairlifts. be sure you have AWD and good AS/ winter tires if 88 is snowed in. More than few times CALTRANS takes a while to open it before opening after it snows.
