Croatia pictures.Croatia, mostly stretching along the coast of the Adriatic, owes much of its beauty to the sea: from several hundred year old seaside towns to the untouched nature of barely inhabited islands, the coast of the Adriatic offers a varied and wonderful landscape. In the pictures below you can find the faces of Krk Island, Pula, Rijeka, Rovinj, Opatija, Split and Zlarin island, with the only non-maritime exception being Zagreb, the capital of Croatia.
