Taking cruise down danube july 1st just curious if river is high enough to allow ships to go down river. Heard last year that when got over to danube and other rivers the cruises were cancelled or cut short.
We spent 18 days in April/May on the Danube from Passau, Germany to the Black Sea and back.
The water level was fine. Later in the year, Summer, there may be a chance that the water level will be lower causing problems for some ships. You have probably read about water levels in August 2003 - This was a very unusually hot Summer in Northern Europe.
We live in Germany and it has been cold and rainy this Spring - I don't think you will have problems early in July.
