Park Güell with audio guide and hop-on hop-off bus tour

Entry to Park Güell with an audio guide, plus a ticket for the city's tourist bus. This combination makes practical sense: the park is located high up, on Carmel Hill, and walking there from the city center is a long and uphill walk. With the bus, that part of the journey is easily solved. Inside the park, the audio guide explains the mosaics, the paths that wind along the hillside, and the viewpoints from which you can see Barcelona. The bus has free stops and is a double-decker bus, so you can get off and on wherever you like for the rest of the day. A note about the reservation: this ticket is non-refundable.
