The Dunajec River is a river in southern Poland. Originating from the Tatra Mountains on the Slovakian border, the Vistula River is injected into the northeast. The total length is about 251 kilometers (156 miles). There are several hydropower stations built. In March 1975, the Czech Republic and Poland adjusted the borders of the two countries along the river, enabling Poland to build irrigation dams in the Czorsztyn area. There is a long stretch of the river between Poland and Slovakia, and we are drifting on this river. The boatman wearing local costumes took us down the river. In the autumn season, the banks of the river were wrapped in yellow to red colors, the left side looked at the autumn colors of Poland, and the right side looked at the beauty of Slovakia. It really felt very beautiful.
