The water reservoir, Hricov, that was built from the river Vah (with a dam which is 9.5 km high and 657 m long ) belongs to the Vah cascade. This river has two source springs: Biely Vah (White Vah), springing under a beautiful peak Krivan, and Cierny Vah (Black Vah), springing under Kralova Hola (it is a hill 1 948 m; "hola" means a hill without trees cover, but grass, rocks...). They flow together at a village called Kralova Lehota. The river ends besides Komarno (a town with 50000 inhabitants) and flows into the Danube River. There are not many big lakes around Slovakia, but there are couple of larger dams. Some of the biggest are Zemplinska Sirava, Liptovka Mara and Domasa. Counties and Towns:

Slovakia is divided in counties that are called “Okresy”. Every county is named by one of the towns that is a part of the county. The capital of Slovakia is Bratislava. It is the largest town with the biggest population. Bratislava plays a prominent role in Slovak economy not only as its economic, commercial, political, diplomatic and cultural center, but also as a center of tourism. Bratislava lies on the banks of the Danube River and at the foot of the Little Carpathians. Its importance as an industry and trade center grows thanks to its strategic position near Austria, Hungary and the Check Republic. Unique architectural, historical, natural and cultural sights make Bratislava a town of culture and tourism. The town lives an intensive intellectual and artistic life, it has a cosmopolitan character and the romantic charm of a town on the Danube River. The cultural life is traditionally varied: 12 theater houses, several concert halls, 22 cinemas, 20 cultural centers, 11 museums and 23 galleries.
The other larger towns in Slovakia are: Kosice, Banska Bystrica, Zilina, Presov, Martin and Trnava. Trnava is Slovakia's oldest town, the first to get a royal charter as a free borough (from Hungarian King in 1238). Though badly marred by modern development, its handsome walled old town, a legacy of almost three centuries as Hungary's religious center, was spruced up for the town's 750th birthday in 1988. Trnava was a center of the Slovak National Revival - some of the first books to use the Slovak written language were printed there. Trencianske Teplice is a smaller town known for it’s spa in West Slovakia. Hiking trails lead into the green hills flanking the resort. There's a thermal swimming pool and five hot sulphur springs in the resort itself. Those with a taste for the exotic should also visit the hammam, a Turkish bathhouse in the middle of town.
