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 Great Segeberg Lake stretches between the town centre of Bad Segeberg and Klein Rönnau. You can cycle, hike, swim in many places and go boating here. The Great Segeberg Lake is just an eight-minute walk from the town centre of Segeberg and is around 1.7 km² in size. The Great Segeberg Lake is divided into two halves by the Spitzenort peninsula. The only real island in the Great Segeberg Lake is the bird island in the northern part of the lake. You can swim in the Great Segeberg Lake at unguarded, free bathing areas such as the floating jetty on the Segeberg spa promenade and at the bathing area at the KlüthseeCamp in Klein Rönnau. There is a bird sanctuary between Stipsdorf and Klein Rönnau, so there are no bathing areas in this area. In addition to the unguarded bathing areas, there is a lido in Bad Segeberg and an outdoor pool in Klein Rönnau. The water quality in the Great Segeberg Lake is excellent, so you can swim here without any worries. In Bad Segeberg there is a rowing club, a sailing club, a boating club and a boat rental for all adventurous water sports enthusiasts. There are other boating clubs in Klein Rönnau and Stipsdorf. On the south bank of the lake there is also an open-air forest grandstand and a play area. In addition to a youth hostel and numerous hotels around the lake, there is a campsite in Klein Rönnau and one in Bad Segeberg. The lake promenade in Bad Segeberg invites you to take a walk along the lake, tired hikers and cyclists can rest on the sun loungers on the sun deck directly on the promenade. If you want to hike or cycle a little further, there are numerous cycle paths in the area. The eight-kilometer circular path around the lake with a detour to the Kalkberg, a wonderful view from the Moosberg and the lake promenade as the destination and starting point is particularly popular. On average, a hike takes 90 minutes. You can of course go much faster by bike, but please watch out for hikers, the paths are sometimes narrow, but easy to ride. https://www.hamburg-tourism.de/sehen-erleben/gruenes-hamburg/parks-gruenanlagen/grosser-segeberger-see-1/

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 path always goes directly along the lake. Beautiful under trees and quite good to drive except for a few roots.
