グロース・レンナウのおすすめウォーキング＆ハイキングルート

🛑 Important Notice 🛑: The beautiful wooden bridge over the Trave River, which is approximately 6–8 meters wide at this point, is closed (as of February 2026). The exact reason is unclear, but structural damage is suspected. Currently, pedestrians can bypass the closure by climbing over the wooden supports, but crossing by bicycle or with a dog is considerably more difficult.

The single trail along the Trave river has several small niches that are well-suited as dog parks.

The salt dome beneath the area around Lake Segeberg and the Sühlfeld is a so-called salt diapir – a geological structure that forms when layers of salt from the depths are pushed upward through the overlying rock. Salt is plastic and less dense than the surrounding rock, which is why it "rises" upwards due to pressure over millions of years. A geological cross-section typically shows: • At the bottom are massive salt deposits (mainly rock salt) that were deposited in deep sedimentary basins. • The salt has been pushed upwards by movements in the subsurface, bulging or breaking through the overburden (sandstones, clays, limestones). • This forms a "stock" of salt, which creates a dome-shaped structure in the overburden. • Tensions are often found around the salt dome, leading to faults and fractures in the rock. • Lake Segeberg lies partly in the depression created by these tectonic movements.

These salt domes are geologically significant because they often contain deposits of natural gas or crude oil, and the upwelling of the salt strongly influences the structure of the subsurface. At the same time, they influence groundwater conditions and can cause problems due to subsidence during mining activities.

After heavy rainfall, this single trail along the shores of Lake Klüthsee is regularly flooded. It's impossible to get through dry without rubber boots. You should also expect overgrown vegetation in late summer.

From this bathing spot, you have a sweeping view of the lake's longitudinal axis. From this angle, it appears significantly longer than its actual 3 km. Tip: On the horizon, you can see the radio tower and the Kalkberg mountain.

Lake Klüthsee is located immediately northeast of Lake Segeberg in Schleswig-Holstein and is significantly smaller and quieter than its more famous neighbor. It is surrounded by forests and meadows, but offers only a few direct access points to the water.

As long as it is as dry as it is now (07/2025), the path is easy to walk, but in rain or persistent rain it is rather difficult.
