Buses
Buses run later than the metro. The metro generally closes between 12:30 and 1:00am (depending where you catch the last train). Limited night buses however run all night. If you find yourself out at the bars late at night in the Puerta del Sol area, you can make your way down to the Plaza de Cibeles bus depot located where Gran Via meets Paseo del Prado. If you are not sure which bus to take, ask one of the drivers or the person at the information booth in the middle of the depot. Expect your bus to be crowded with other night owls. Everyone on the last bus home is usually really wonderful and is still having a good time, and it can be great place to meet new people.
