Montevideo's international airport, Aeropuerto Carrasco, is 20km (12.4mi) east of the city. Besides the usual international carriers, commuter airlines also provide services to Argentina. The internet-based Gol Airlines has cheap flights to Porto Alegre, Brazil.
Ferryturismo does bus-ferry combinations to Buenos Aires, via Colonia (6hr), and with the faster Sea Cat (4hr). It also has a branch at Terminal Tres Cruces. Buqueaviones (high-speed ferries) cross to Buenos Aires from Montevideo (2.5hr). Cacciola, at Terminal Tres Cruces, runs a bus-launch service to Buenos Aires (8hr) via Carmelo and the Argentine Delta suburb of Tigre.
Montevideo's Terminal Tres Cruces (cnr Bulevar Artigas & Italia) has decent restaurants, clean toilets, a left-luggage facility, a casa de cambio (foreign-exchange house) and ATMs.

Montevideo's improving fleet of buses go just about everywhere throughout the city. They are cheap and tickets are available from the bus driver or conductor, who will ask for your destination. Hiring a car is almost as expensive as in Argentina and not necessarily practical in a place as small as Montevideo. Taxis are safe and metered but can be expensive, with additional surcharges for luggage and travel on weekends, holidays and late at night.
