A nice opportunity to take a short rest on one of the many benches by the lake and enjoy the silence

From here you can admire the beautiful Wehmer Dose with its impressive, rewetted raised moor areas in the north. -My favorite spot- But if you turn around, you can also discover the picturesque Theikenmeer in the south.

The tour was very varied despite its manageable length. I can recommend it at any time of year. The last time I was there (October 2024) the hiking trails were in top condition. The grass was mown and most of the wet spots were easy to pass. I have to give a big compliment to the hard-working spirits.

A short side path leads to the bird watching hut. A few steps take you to the observation hut with seating and information boards about the birds to be observed. You have a wide view over the Theikenmeer.
