Trail description: The trail begins and ends at the canoe jetty. Canoeing should be made dependent on weather conditions. In case of strong wind we should give up canoeing because of high waves which may pose danger to our safety. In case of mild wind, which may be also a hindrance on open water surface, we should canoe only near the canoe jetty. Under windless conditions or in case of very mild wind we can use the whole Lake surface for canoeing. All safety regulations must be adhered to and we should have a safety jacket in our equipment.

The most important bird species to be seen or heard during the best season for birding: the Eurasian bittern, the common goldeneye, the greylag goose, the great crested grebe, the red-necked grebe, the great reed warbler, the common tern, the mute swan, the gadwall.


The best observation points: 1 – canoe jetty – view over the southern part of the Lake where in April and May mating Eurasian bitterns are to be heard. Moreover, from the observation tower great-crested grebes, sometimes even red-necked grebes, as well as Eurasian coots, greylag geese, swans and other aquatic birds can be seen; 2 – a good spot for the observation of aquatic birds. With a bit of luck Eurasian bitterns flying from one reed to another may be seen. At this point grebes, ducks and other aquatic birds may be seen.
