It’s easy to see why Barcelona is the most-visited city in Spain. As the capital of the country’s Catalonia region, this cityscape’s cultural mosaic pieces together a 2,000-year-old hodge-podge of sun-drenched beaches, cutting edge architecture and a world-renowned dining and drinking scene.

Get lost in the whimsical gardens of Park Guell or savour a chef-led Catalan cooking class. Browse art collections dedicated to Picasso and Miro – or ride a cable car to the top of Montjuic Hill, relishing citywide views along the way.

Head to Plaza de la Reina in the citys old town and do some people-watching over a fresh glass of horchata, a classic Valencia beverage made from almond milk with cinnamon and spices, or take a picnic lunch of fresh pears and local cheese to the quiet Turia Gardens.
