The Ihlsee is located in the northwestern part of the district town of Bad Segeberg on the northern edge of the Kleinniendorf district and is part of the designated Ihlsee and Ihlwald nature reserve. The origin of the lake has not been fully investigated. Either the depression was formed after the Ice Age due to dead ice or it was created as a sinkhole by the collapse of a cave in the Segeberg salt dome. Today the lake has an area of around 29 hectares and stretches 450 m from north to south and around 850 m from west to east; the shore is 2.25 km long. Along with the Bültsee and the Garrensee, the lake is one of the few nutrient-poor lakes in Schleswig-Holstein. The lake is located in a depression and has no inflow. It is fed only by groundwater and inflowing surface water (precipitation). To the north of the bathing area is the outflow that connects the lake to the Great Segeberg Lake. The lake can be walked around, but there is no path along the lake. There is a bathing area on the eastern shore that has existed for decades. The bathing water quality is regularly monitored and in recent years has been rated as very good to good. There is a residential area on the northern shore. On the western and southern sides, the Ihlwald, a swamp forest, dominates the shoreline. From 1911 to 1961, there was a Kiel-Segeberg narrow-gauge railway station at Ihlsee, the tracks of which were removed in 1962. The Ihlsee was declared a nature reserve in 1950 because of its special features. The lake is a particularly nutrient-poor body of water, which gives rise to rare flora. Today, the lake is part of the Ihlsee and Ihlwald nature reserve and has been part of the Natura 2000 protected area network since 2006. https://de.wikipedia.org/wiki/Ihlsee

The Brenner Moor is the largest salt marsh in inland Schleswig-Holstein. The salinity of the salt springs partially reaches that of the North Sea. A jewel of nature but very busy on weekends. Still a real highlight. The crossing is only possible thanks to the laid planks. However, cycling is prohibited

The Brenner Moor is the largest inland salt marsh in Schleswig-Holstein. It is located in the district of Stormarn in the town of Bad Oldesloe in the Trave lowlands and has been declared a nature reserve. What is special about the Brenner Moor are the brine springs that rise from a depth of approx. 500 meters and have their origin in a salt band that presumably stretches from Segeberg via Tralau and Bad Oldesloe to Lübeck. The plant communities and the animal world of the Brenner Moor are shaped in a special way by the unique occurrence of salt springs inland. The salty environment attracts plants that are otherwise only found near the coast, e.g. B. rush (Juncus gerardii) and beach trident (Triglochin maritima). In some places the water has a salinity that corresponds to that of the North Sea. In less saline parts of the nature reserve, reed beds, among other things, grow. https://metropolregion.hamburg.de/kulturlandschaften/4471072/brenner-moor/

Originally, the salt pond of the saline was used to store wood, for the wooden rods that were used to conduct the energy generated by water and wind to the pumping stations. After Oldesloe became a spa, in 1824 the saline pond, which was fed by natural salt springs, cleaned, enlarged and integrated into the infrastructure of the spa park. Today it is used as a fishing pond.
