Casa Batlló and Sagrada Familia: Skip the lines, with a guide, and accessible by metro

A guided tour of Gaudí's main works in Barcelona, with the two most important tickets already reserved. It starts at Casa Batlló, with a scheduled time and no waiting in line. From there, you walk along Passeig de Gràcia to Casa Milà, La Pedrera, which you can see from the street: the undulating stone facade and the balconies' grilles are better seen from that distance than from the inside. The last leg is done by metro, not by bus, which is how the city really moves and avoids getting stuck in the traffic of the Eixample. At the Sagrada Familia, the guided tour enters the interior, which is where the forest of columns and the stained glass windows suddenly explain everything you've been seeing from the street. It can be canceled up to the deadline indicated in the reservation.
