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.

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.

The cute little of village of Weissenkirchen is situated on the Danube in the picturesque Wachau Valley, and takes its name from a fortified 14th century Gothic church. It won’t take long to explore the village itself, but nearby attractions include the beautiful abbey at Melk.

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.

Formerly the centre of the Habsburg Empire, Vienna is as grand a European capital as you can imagine, jam packed full of thrusting, bombastic buildings that stand as a reminder of Austria’s glorious imperial heyday.

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.

Esztergom was the birthplace of St Stephen, the first king of Hungary, who was crowned here in 1000 AD and converted the kingdom to Catholicism. The picturesque town is dominated by the magnificent Basilica, which towers high above the Danube.
