Ungeheuersee

Because the lake is part of the only raised bog in the Palatinate Forest and is important for the species-rich flora along its shore and on its floating island (including cotton grasses and orchids), it was placed under protection in the 1930s as a natural monument.

The Krumbach valley is designated as a protected landscape as far as the edge of the Haardt uplands.

The Ungeheuersee was laid out towards the end of the Middle Ages or Early Modern Period as a drinking pool for cattle.

The monks of Höningen Abbey also sank their silver bells in the lake for security, but these, too, remain lost.

In recent years, intensive touristic use of the reservoir has led serious damage of the natural monument.
