Mill B Parking Options

There are several, although limited, parking options. The Mill B South parking lot is on the right side of the road at the beginning of the S-Turn, but it is normally closed during the winter. You can also park in the small lot that is inside the S-Turn (if it is plowed). The best option is usually to park in a safe location on the side of the road.
