Dalmatia is a region of Croatia on the eastern coast of the Adriatic Sea, spreading between the island of Pag in the northwest and the Bay of Kotor in the southeast. The inner Dalmatia (Dalmatinska Zagora) stretches from up to fifty kilometers inland in the north to just a few kilometers in the south. Dalmatia is currently composed of four counties, capital cities of which are Zadar, S<caron>ibenik, Split and Dubrovnik. Other larger cities in Dalmatia include Kas<caron>tela, Sinj, Solin, Omis<caron>, Knin, Metkovic´, Makarska, Trogir, Ploc<caron>e, Trilj and Imotski. The larger Dalmatian islands are Dugi Otok, Ugljan, Pas<caron>man, Brac<caron>, Hvar, Korc<caron>ula, Vis, Lastovo and Mljet. The larger Dalmatian mountains are Dinara, Mosor, Kozjak and Biokovo. The rivers are Zrmanja, Krka, Cetina and Neretva. Due to the way sea currents flow and how the winds blow on the Adriatic, the sea water is much cleaner and much warmer than it is on the Italian side. The Dalmatian concordant coastline also includes an immense number of coves, islands and channels. This makes it a really attractive place for nautical races, and nautical tourism in general. There's a fair number of marinas as well. Dalmatia also includes several national parks that are tourist attractions in their own right: Paklenica karst river, Kornati archipelago, Krka river rapids and Mljet island within island.
