Barcelona is often referred to as one of the most beautiful cities in Europe. It's not hard to see why — travelers flock from around the world to see the iconic Sagrada Família church and other modernist landmarks designed by Gaudi, such as Palau Güell and Casa Mila.

Ciutat Vella, the gothic quarter of Barcelona, is the oldest part of the city. It includes Las Ramblas, the famous tree-lined boulevard that cuts through the heart of the city. The La Boqueria Food Market is a wonderful place to sample local delicacies. Barcelona is home to numerous museums, such as Gaudi House Museum, the Picasso Museum, Museu Nacional d'Art de Catalunya, and Poble Espanyol, the open-air architectural museum. All offer unique experiences.

Barcelona has a host of green spaces and parks, too. Filled with vivid colors, decorative walls and murals, and great views, Park Guell is also home to flocks of monk parakeets. Parc de la Ciutadella features plenty of picnic areas and a stunning fountain; the magic fountain of Monjuic is another great spot — it’s lit up at night for a Technicolor experience you won't forget. If you like to hike, the Sants-Montjuic park area offers amazing city views from the top of the mountain. Climb to Sagrat Cor on the summit of Mount Tibidabo for more fantastic views of the city and impressive architecture.
