The DDSG (Erste Donau-Dampfschiffahrts-Gesellschaft; First Danube Steamer Company), one of the oldest shipping companies in the world, was founded in 1829 in Vienna. In 1834 the first DDSG steamer reached the Black Sea, three years later regular services had been established between Regensburg and the Danube delta. Today, as the national Austrian Danube shipping company, the DDSG operates a fleet of passenger ships, a number of which are equipped with cabins. A hovercraft between Vienna and Budapest provides a faster service.
Among the traffic crossing the border between Germany and Austria are the boats (from May to September) from Passau to Linz and Passau to Vienna. It is possible to make the outward journey by boat and return
by bus or train or vice versa. Within Austria itself there are excursions from Linz to Vienna and from Vienna to the Wachau. The excursions often feature a program on board (dancing) or walks ashore (town tours and visits; visits to festivals and musical events; in Dürnstein a visit to a typical Wachau cellar completes the tour of the town). Another route between Germany and Austria follows the Rhine-Main-Danube waterway from Nuremburg to Vienna.
From Easter to October there are round trips which leave the DDSG station at Schwedenbrücke, heading up the Danube canal to Nussdorf in the Danube river, past the Danube Tower and UNO-City to the Prater and back again (about 3 hours duration). Evening cruises are arranged from Thursday to Saturday in summer. Shorter 1.5 hour excursions are also possible.
There are also a number of possible excursions by DDSG boats from Vienna to Eastern Europe and the Black Sea. As well as trips from Vienna to Budapest (can also be combined with a visit to Lake Balaton) and from Vienna to the Iron Gate there are boat trips from Vienna to Sulina on the Black Sea which are more like cruises. The former Soviet ship MS "Volga" is on permanent charter to DDGS. It sails from Vienna to Ismail on the Danube delta, where passengers transfer to the MS "Ajwasovski", which continues via Yalta (Crimea) to Istanbul. The trips to the Danube delta and Istanbul can be combined with a flight either from Vienna to Constanta on the Black Sea coast or to Istanbul or the other way round. Before traveling by boat to Hungary or the Black Sea passengers should inquire about passport and visa regulations.
