Billings' downtown area can be a bit confusing for visitors, as it was designed on a grid system with numbered avenues increasing numerically both to the north and south of Montana Avenue, and numbered streets crossing it from east to west. The central area is compact and can be explored on foot. Most visitors, however, prefer to rent a car to explore the city and outskirts. The city bus service is the Billings MET Transit, which is easy to use. MET buses stop at most corners and at stops with a distinctive blue and green sign. Exact fares are required, paid to the driver. Buses run from 5.50am to 6.40pm on weekdays and from 8.10am to 5.45pm on Saturdays. There are no buses on Sundays or major public holidays.
