Bus
Night buses are known as ‘búhos’ (‘owls’), have different routes to those of the conventional bus service and leave from Plaza de Cibeles. Frequency of service varies depending on whether it’s a working day or a public holiday. On weekdays they operate from around midnight to 5.30am and the frequency of service is about every 35 minutes. At weekends they operate until 7am and leave every 20 minutes.
Madrid City Tour, a tourist bus that travels around the city, is a good option for visitors who are short of time. There are two different routes, and a night service in the summer. It allows you to see the main sights for €21 for an adult ticket.
