Protection Forest, Park
Everybody takes delight in the colourful sight of water-lilies covering the surface of the lake. The red Indian water-lily was brought to Hungary in 1898 by Sándor Lovassy, the teacher of the Academy of Economy in Keszthely.
These days the indigenous white water-lily of the Lake occurs mostly in the drainage canal due to the purification. The strictly protected plants are in bloom from the beginning of summer to the end of November. Water-lilies are significant for two reasons; in one hand, their leaves slow down the evaporation of the lake and on the other hand their runners all around at the bottom of the Lake protect the medicinal mud.
The Berki Study Trail still unknown by most people, however, there are several sights worth visiting in the course of a walking tour. The Trail covers the Lake of Hévíz and the surrounding moor as well as its flora and fauna which is unique not only in Hungary but in Europe as well.
