Beautiful narrow forest path along the Schwentine. Also highly recommended if you want to go to Gut Rastorf, as you avoid the incline on the sandy path (Rastorfer Weg), which is not so easy to navigate.

The "Timmdorf" jetty is used both on the outward and return journey of the 5-lake trip from Malente to Plön. Passengers boarding here redeem their tickets on board the ships. In principle, the tour can be started, interrupted or ended at any landing stage. A hiking tour can also be wonderfully combined with a boat trip. The piers of the White Fleet, the places to stop for refreshments and the beautiful hiking trails are close together - as if made for excursions into nature. There is a very idyllic place for a picnic between the Timmdorf landing stage and the bridge.
