A short hike through the mixed forest, especially on hot and sunny days. It's ideal for accompanying a dog, as there are play and swimming opportunities both at the Rantzau stream and at the small forest lake.

The ring wall castle 'Kaaksburg' dates back to the 8th or 9th century. Its oldest known documentary mention dates from 1560-1576. The oval ring wall with a diameter of 80 or 100 m and a height of around 5 m was raised from dark earth, while the ground in the surrounding area is sandy, which is why it was assumed that the material came from the Bekau, which flows past in the southeast. At that time, the Bekau was navigable at least as far as the castle and was influenced by the tides until it was embanked; the area around the castle was still swampy and marshy at that time and was occasionally flooded. It was therefore assumed that the castle was built in this strategically favorable position to control the waterway. According to a folk legend, it once served as a base for pirates - sometimes Klaus Störtebeker is mentioned. While the country road between Itzehoe and Schenefeld used to bypass the ring wall to the east, today's L 127 runs right through the ring. https://de.wikipedia.org/wiki/Kaaksburg

The Kaaksburg was a Saxon ring wall that was built around the year 800. It had a diameter of 80 m and 4 m high earth walls. The castle complex was intended to secure a trade route across the Bekau. Today, a wide street runs through the middle of the castle complex and cuts the ring wall in two. Right next to the castle is a rest area with a snack bar.

The Schierenwald is an 821 hectare forest in the Steinburg district in Schleswig-Holstein. A small part of 22.2 ha has been designated as a natural forest cell since 2008 and has not been managed since 1979. The forest area lies in the northern area of the municipality of Hohenlockstedt and is located between the villages of Lockstedt and Silzen. There are large occurrences of amphibians in several bodies of water (common toad, common frog, pond newt, crested newt). The rivers flow either over the Rantzau or the Mühlenbarbeker Au. The forest, which is particularly large and compact for Schleswig-Holstein, is home to older oak and red beech stands, predominantly coniferous forest and mixed coniferous forest stands that are over 100 years old. The forest is a state forest owned by the State of Schleswig-Holstein. Source: https://de.wikipedia.org/wiki/Schierenwald

The approximately 77 hectare area was bought in 2005 with the financial participation of the municipality of Mehlbek, the Nature Conservation Foundation and the nature conservation authority of the Steinburg district for the benefit of nature conservation. Since then the water level has risen continuously and has now reached its final height. The natural oasis became a large lake and is constantly changing. There is always something new to discover for nature lovers: especially beautiful, the small cormorant population. Source: https://www.bund-steinburg.de/radtour-2016.html
