Following hotel or port pickup in the morning, take a panoramic tour of top Barcelona attractions including the Mountain of the Jews (Montjuic), Montjuic Castle, and the Olympic Stadium.
Then, focus on the masterpieces of Antoni Gaudi by visiting the famously unfinished La Sagrada Familia and Casa Batlló, outside of which you have ample time to take photographs.
After traveling down Passeig de Gracia, sail past the long lines outside of Park Güell, and take a guided tour of the public space. Following a break to buy lunch (own expense), continue on to Montserrat to explore the mountaintop monastery.
Your guided tour concludes back at your original departure point.
