Once you meet your guide, you can get ready for a bike tour that will show you not only the tourist hotspots but also take you to lesser-known hidden gems. The tour starts in the Gothic quarter (some of which remained intact from the middle-ages) from where you will cross the Eixample neighborhood (Gaudi's favorite). Afterward, enter Raval (a red-light district for many centuries), right next to the Chinese neighborhood. Your last stop will be la Barceloneta, a seaside area, where you can find a mix of disco clubs, beach bars, and working-class buildings. Your tour ends back at the spot in the city where your tour started.
