Taking the bus isn’t as quick as the metro, but if you’d like to see some of the city while you move it’s worth figuring out a route that suits you. Most buses run between 6.00 and 23.00. Night buses run after that and always cross Plaza de Cibeles. Even though buses have a lane to themselves, it might be best to avoid them at rush hour. And if you’re keen to see the sights it’s worth checking out the tourist bus.
