The Danube is the largest Western European river with streamlined shipping. Barges and dry cargo vessels go along the river throughout the navigation, and motor ships of tourist companies make tours of the Danube in the summer months, from May to September. The river is very picturesque, a gift for lovers of leisurely cruises and travelers who try to visit the maximum number of countries in one go. The Danube is quite suitable for this purpose; ten European countries are located on its way.
The states, on the territory of which the Danube river flows, start from Germany, the source is located there. The mountains of the German Black Forest give rise to a great river. The birth of the Danube is surrounded by mystery. After about thirty kilometers, the river suddenly disappears. All the water, to the last drop, goes underground, seethes there and rushes about in order to break out after 12 kilometers in the form of a powerful source, which was given the name Aahsky key. In 1876, a check was made for this key; it turned out that it is fed completely and completely with water from the source of the Danube.
But the most interesting thing is that the Aach key gives all the water to the Aach Radolfzeller river, which takes it to Lake Boden, and from this lake the Rhine River originates, which is one of the largest waterways in Germany. Nevertheless, the available water resources are quite enough for the Danube itself. After a turn at the German Regensburg, the river gains strength, gradually becomes full-flowing and slowly flows further. Having passed Austria and the Vienna Depression, the Danube River flows for some time along the border of Slovakia with Hungary. Rather, it becomes a natural border between the two countries on a fairly long stretch. Then, in the Budapest area, it abruptly turns south.
Now the path of the wonderful European river lies to the south, along the way the Danube divides the Hungarian capital - Budapest - into two cities, Buda and Pest. I must say that Buda and Pest, together with the Danube, form one of the most beautiful places on the globe. The Hungarian capital is also the world capital of health baths. Many thermal springs brought Budapest to one of the first places in the therapeutic rest industry, and the Blue Danube helped this city.
After the Danube crosses the southern border of Hungary, it again becomes the natural border between the two countries, this time Serbia and Croatia. However, soon the Danube River turns sharply to the left, leaves the border and meets the beautiful old city of Belgrade. There, the Danube receives one of its main tributaries, the Sava River. Replenished, flows further towards Romania. And again, for the umpteenth time, the Danube River becomes a natural border between the two countries. Throughout the length of the contact between the Romanian territory and Bulgaria, the border runs along the Danube.
And just a little before reaching the shores of the Black Sea, the Danube River turns north to touch the most extreme southern point of Moldova and a little walk on Ukrainian land. It is divided into several arms, forming a classic triangle of the river delta, runs the last few kilometers and calmly pours its tired water from a long journey into the hospitable Black Sea.
