Budapest is one of Eastern Europe’s most appealing cities, a vibrant and welcoming capital that straddles the Danube. The history of Budapest has been somewhat turbulent, but plenty of beautiful buildings survive, including the imposing Parliament and iconic St Stephen’s Basilica.

Bratislava, Slovakia’s quaint little capital, straddles the Danube close to the border with Austria and Hungary. The compact old town is the best place to begin your exploration, before heading up to the hilltop castle for commanding views of the city and surrounding countryside.

Vienna is jam packed full of thrusting, bombastic buildings that stand as a reminder of Austria’s glorious imperial heyday. From mid-November the city's squares are transformed into magical Christmas markets, where fairy lights twinkle and the air is heady with aromas of sizzling sausage, gingerbread and Glühwein.

Krems sits on the river Danube at the eastern end of the beautiful Wachau Valley, surrounded by vineyards. It’s an attractive old town, with pretty cobbled streets and a good selection of galleries and museums, as well as some excellent restaurants.

The city of Linz is included on river cruise itineraries due to its proximity to Salzburg, which is where you’ll most likely be headed. Salzburg’s Altstadt attracts millions of visitors every year with its fairytale skyline of domes and spires, and the city is renowned as both the birthplace of Mozart and the setting for ‘The Sound of Music’.

The pretty Bavarian town of Passau, situated close to Germany’s border with Austria, enjoys a unique setting at the confluence of three rivers: the Inn, the Ilz and the Danube. The narrow cobbled streets of the handsome old town, the Altstadt, are quite delightful.
