The further you get from Bad Segeberg, the quieter and more secluded the path becomes – at least in winter. After rain or during thaws, it can sometimes be very muddy.

On hot days, the shady paths are a welcome change 😉...

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

On the eastern shore of the Ihlsee, the lido invites you to swim in wonderfully clear water. For small bathers, the spacious, shallow non-swimmer area is ideal for playing and splashing around. In addition, wide lawns and the diving tower with water slide offer plenty of fun for the whole family or especially for a refreshment and cooling down during your tour. Free parking is also available. http://ihlsee-strandbad.de/
