It is a surprising mosaic of diverse environments and a colorful animal world... A huge lake. A world unto itself. The huge Lake Balaton was formed long ago in a world of volcanoes and ice ages. The largest inland lake in Central Europe lies in the heart of Hungary, on the plains stretching east of the Alps. Fresh water flows into it via the Zala River and a number of smaller seasonal streams. These waterways carry precious cargo to the lake. Countless fish swim here to their traditional spawning grounds. The dense local vegetation is popular with herons and cormorants; they have only one concern: to collect enough material to build their nests. So many young birds grow up here that the marshes are teeming with life. Just like the entire lake and its immediate surroundings, which are truly full of natural beauty.
