Ponds located in the Diekseeholm forest area, which were formerly used for fish farming. These natural attractions in Malente were created in 1869 for the breeding of noble fish. The ponds are fed by fresh spring water from the "Diekseeholm" forest area. They are connected to each other by small streams and channels. The ponds get their name because the surrounding trees are particularly beautifully reflected in the calm, smooth water. In the immediate vicinity of the Spiegelteiche (Mirror Ponds) is one of Malente's Kneipp facilities: a natural water treading pool and an arm-kneading pool.
