January 13, 2026, Cliff Path at Bülk Lighthouse

A beautiful path right along the cliffs... if you prefer, you can also walk directly along the water... You can see the green and white lighthouse from afar and enjoy magnificent views of the water.

The Westensee (elevation 6 m above sea level) is located in the Achterwehr district in the Rendsburg-Eckernförde district. It is the fifth largest lake in Schleswig-Holstein and is characterized as a lime-rich lowland lake with a relatively large catchment area without pronounced temperature stratification. With its location between the cities of Kiel and Rendsburg, it forms the center of the Westensee Nature Park. It drains into Schleswig-Holstein's largest river, the Eider, and also reaches the Kiel Canal via the Achterwehr shipping canal.

There are two alternative paths here: the path on the beach and the path on the cliff. Use the paths depending on the weather.

North of the Eider, the hiking trail runs directly along the river. This piece is very varied and offers beautiful photo moments in every season. There is a dog bathing area and a 🅿️.
