As with any city trip, good walking shoes are a must when traveling to Barcelona. Additionally, you should consider the season and the weather forecast when packing your suitcase. For example, good sunscreen, sunglasses, summer clothing, and open shoes are indispensable during the summer. In spring and autumn, you need a transitional jacket and a small umbrella in case it rains. Winters in Barcelona are fairly mild compared, but a winter coat, a scarf, and gloves are often not superfluous.
