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.

There was also a cormorant colony on an island in Lake Selent, which was later abandoned and subsequently recovered.
