Discover the whimsy of the great Catalan architect Antoni Gaudi on this five-hour art lovers tour of Barcelona, which may be unsuitable for those with walking difficulties, due to the locations and time constraints. First stop of the day is the glorious Park Guell, which showcases Gaudi's signature mosaics and quirky designs, such as the serpentine bench and multi-colored mosaic dragon that sits at the entrance to the park. Then stroll around the famous La Sagrada Familia, Gaudi's unfinished yet strikingly modernist church which has been under construction since 1882. Admire the many towering spires, stained glass windows and intricate designs before moving along to the Passeig de Gracia, a stunning promenade that's home to many of Gaudi's buildings.
