Do I need Four Wheel Drive rental car to drive from the Bozeman Airport to Big Sky in the winter? Yes.
This photo was taken while exiting the Bozeman Airport, from the car. The foreground is the road. The next 50+ miles to Big Sky will be worse. Please be safe and make sure you either have a rental car with 4WD or AWD and good tires, or your transportation company/ UBER/ LYFT has 4WD or AWD with good tires. Safety is a necessity in these condition!
