There is extensive bus service in the larger cities. Quito has a modern ‘trolebus’ (busses that run on separate tracks throughout the city like trolleys) system that is fast and cheap. Local buses are usually slow and crowded, but they are also very cheap. You can get around most towns for $0.25. Local buses often travel to nearby villages, and riding along is a good, inexpensive way to see the area. Outside of Quito the concept of a fixed bus stop is pretty much nonexistent. Buses stop (or at least come to a slow roll) when people flag them down. When you want to get off a local bus, yell ‘¡Baja!,’ which means ‘Down!’ (as in ‘the passenger is getting down’). Another favorite way of getting the driver to stop is by yelling ‘¡Gracias!’ (‘Thank you!’), which is unmistakably polite.
