As part of the Holstein Switzerland Nature Park, the Tarbek Moor with its special charm is a popular excursion destination that gives you a variety of impressions. With its diverse composition of ponds and vegetation-free peat banks, it offers undisturbed insights into a mysterious-looking habitat. A moor birch forest borders dark ponds surrounded by snakeroot, dead birch trees in water-filled peat pits rise picturesquely into the sky and fields of waving cotton grass are reminiscent of images from Nordic legends. In the 131-hectare area, which was previously used as a peat extraction area, remnants of this use can still be seen today and carefree cycling and hiking from the Tarbek Moor to the Ihlsee in Bad Segeberg is possible both along former routes that have been preserved to this day and along the railway embankment that connected Bad Segeberg, Bornhöved and Kiel until 1960. https://www.blunkerbach-sh.de/tarbeker-moor

The Wittenborner Heide nature reserve remained nutrient-poor and unfertilized due to its previous use as a military training area. This resulted in a diverse landscape of heathland, moors and sparse forests that provide a habitat for many species. You can hike through a very beautiful landscape that is always worth a visit.

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 most popular natural monument is the Kalkberg, Bad Segeberg, a 91-meter-high gypsum mountain known for its unique geology, panoramic views, and extensive bat caves. Visitors also highly appreciate Lake Ihl, a nutrient-poor lake within a nature reserve, and the Wittenborn Heath Nature Reserve, which offers diverse landscapes including forest and heathland.
The Kalkberg is geologically unique because it's primarily composed of gypsum and anhydrite, not chalk, and is continually uplifted by an underlying rock salt dome. It's one of the few elevations in Schleswig-Holstein not formed by glacial activity. Beneath it lies a vast cave system, one of Europe's most significant bat habitats, providing winter quarters for around 30,000 bats. You can also enjoy panoramic views from its summit.

For an interactive experience, the Noctalis Bat Centre, located directly at the Kalkberg, offers exhibitions where you can learn about bats and observe living tropical bats.
The Ihlsee is one of Schleswig-Holstein's most important nutrient-poor lakes, supporting rare and critically endangered plant species. The surrounding Ihlwald (forest) is allowed to develop naturally, providing habitat for various bird species. The area is a protected nature reserve and a Flora-Fauna-Habitat (FFH) area, making it an exceptional site for observing rare flora and fauna.
