The Wachau is an Austrian valley with a picturesque landscape formed by the Danube river. It is one of the most prominent tourist destinations of Lower Austria, located midway between the towns of Melk and Krems that also attracts "connoisseurs and epicureans" for its high-quality wines. It is 36 kilometres (22 mi) in length and was already settled in prehistoric times. A well-known place and tourist attraction is Dürnstein, where King Richard I of England was held captive by Leopold V, Duke of Austria. The architectural elegance of its ancient monasteries, castles and ruins combined with the urban architecture of its towns and villages, and the cultivation of vines as an important agricultural produce are the dominant features of the valley.

Tourism in Austria forms an important part of the country's economy, accounting for almost 9% of the Austrian gross domestic product. Austria has one guest bed for every six inhabitants, and boasts the highest per capita income from tourism in the Organisation for Economic Co-operation and Development. As of 2007, the total number of tourist overnight stays is roughly the same for summer and winter season, with peaks in February and July/August.
