グロース・レンナウ周辺のおすすめ交通量の少ないサイクリングルート

🛑 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.

Construction of the new bridge began in November 2025.

Here you really can relax!

The Nienwohlder Moor lies on the watershed between the North Sea and the Baltic Sea.[2] It drains to the west into the Lankau, to the south into the Alte Alster, and to the north into the Norderbeste. The nature reserve, which is managed by the Schleswig-Holstein State Hunting Association with the exception of the areas owned by the State Forestry Administration[5],[6] can be almost completely circumnavigated on hiking trails, along which information boards are posted at several locations. In the west, a hiking trail runs through the protected area in the area of the Lunden, a towering moraine ridge.

Today, typical raised moor vegetation can once again be found in the nature reserve, including round-leaved sundew, narrow-leaved cottongrass, bladderwort, white beak sedge, sedge cottongrass, cranberry, as well as cross-leaved heather, rosemary, and common heather. The nature reserve also represents an important habitat for birds. Various wading birds such as the curlew and the common snipe, as well as ducks such as the shoveler, teal, tufted duck, and garganey, as well as meadow pipits, whinchats, and stonechats, are native here. Marsh harriers and short-eared owls can also be found here. The undisturbed moorland is a refuge for cranes, which are now breeding here again. Various woodpecker species, red-backed shrikes, and songbirds are native to the wooded moorland areas. The nature reserve also provides a habitat for various amphibians and reptiles, as well as insects such as dragonflies and butterflies.

The moor was renaturalized in the 1980s through rewetting measures.[2][3] Today, in the area of former industrial use, it is an open raised bog with numerous water-filled peat pits, surrounded by a bog forest. The farmer's hand-cut peat pits at the edge of the moor are often water-filled. Sphagnum moss quaking grassland grows here, and the peat pits are slowly silting up. Further areas are occupied by grassland and forest. Some of the grassland is extensively grazed by robust cattle.[4] Some areas are still intensively used for agriculture, including one arable area.

Peat extraction, first documented in 1804, was initially carried out by peat-cutting by peat-farmers, and the peat was used as fuel. During the Napoleonic Wars of 1806–1813, peat was also shipped to Hamburg via the Alster. In the 20th century, peat extraction became an industrial operation. From 1951 to 1976, the white peat was extracted from an area of 84 hectares, initially by hand and later by machine.[2] East of Nahe, there was a peat loading point on the Elmshorn-Barmstedt-Oldesloe railway.

The nature reserve is located northeast of Hamburg between the towns of Nienwohld, Nahe, Itzstedt, and Sülfeld. It protects a drained and largely peat-extracted raised bog area, which is the largest and best-preserved raised bog remnant in Schleswig-Holstein.[2] To the north, it borders the former Elmshorn-Barmstedt-Oldesloe Railway line.
