Ukraine

Ukraine is a relatively large country with an area of 603000 km² in Eastern Europe. It borders Russia to the east, Belarus to the north, Poland, Slovakia, Hungary, Romania and Moldova to the west.
The capital and most populous city of Ukraine is Kyiv. The territory of Ukraine has been inhabited since 32000 BC, but in its current borders Ukraine has only existed as a self-ruled country since the dissolution of the Soviet Union in 1991.
The territory of Ukraine consists mostly of plains. The only mountain range worth mentioning are the Carpatians, in the west of the country, with peaks exceeding 2000m.
Ukraine is not exactly a tourist destination. While no visa is needed for EU nationals, getting into Ukraine by car involves long waiting times at the borders. We managed to cross into Ukraine from Poland in less than three hours, but when leaving Ukraine we spent almost 15 hours at the border to Hungary.
Ukrainian roads are a bit of a mixed bag. While the roads connecting the largest cities (for instance Kyiv and Lviv) are reasonably good, secondary roads can be quite bad in some sections. However, at the time of visiting, roadworks were ongoing, so it's likely that the overall condition of Ukrainian roads will continue to improve.
Compared to countries more in the centre and west of Europe, there are fewer things to see in Ukraine, probably also due to the lower population density. The capital Kyiv lacks a clearly identifiable historic core. On the other hand, Ukraine is interesting to visit, in the sense that it is not the typical destination overrun by tourists, so the visiting experience will be a different one.
