If you want to enjoy the best views over Barcelona city, there is no better way than going up to "Collserola" mountain. I offer you the possibility to take a bike ride crossing the city through the "Carretera de les aigues" road with fully views on the city and sea. The tour gives you a panoramic city views showing the Sagrada Family, the Spotify Camp Nou and the Montjuic castle, and even on the clear days you can enjoy the Montserrat mountain views. Several stops are included during the tour to take pictures and to give you some explanation about Barcelona history and its most important places. Do not doubt, this is the best bike ride you could ever imagine in Barcelona.
