The Dieksee promenade takes you from the Malente Wildlife Park to the Diekseeholm forest. The Dieksee promenade runs along the western shore of the 368-hectare Dieksee lake. Here you will find many of Malente's hotels, guesthouses, and health clinics. Redesigned in 2007, the promenade consists partly of paved stone slabs and partly of hard-packed sand. During the construction work, a floating pontoon for events was installed near the pier for the 5-Lakes Cruise and Kellersee Cruise. An additional wooden walkway was also added to the promenade. Terraced platforms have been integrated along the embankment, offering a particularly beautiful view of the Dieksee.

In Plön and the surrounding area, there are cormorant colonies that sometimes cause damage to vegetation and fisheries. The island of Sterin in the Great Plön Lake is a well-known example of the destructive effect of cormorant droppings, which virtually destroy vegetation. There was also a cormorant colony on an island in Lake Selent, which was later abandoned and subsequently recovered.
