Halbinsel Holnis

Halbinsel Holnis is a protected nature reserve on the Flensburg Fjord with steep cliffs, sandy shores, and salt marshes spread across the landscape. The land includes forest areas, open dunes, and several inlets that create different habitats in one place.

The area was once separated from the mainland until being connected in the 1920s through drainage work. Official protection followed decades later in the 1990s under management of a nature conservation organization.

The peninsula shows traces of brick-making heritage visible in the landscape today, with old clay pits still marking the terrain. Walking through, you notice how these former extraction sites have become part of the natural environment.

Walking paths cross the area leading to viewpoints and along the coastline, with some sections passing through marshland or sandy terrain. Proper footwear and care on unmade paths are recommended, especially after wet weather.

The southern section holds remnants of an artificial lake called Gross Noor that was drained away during the 1920s through systematic engineering. This radical change to the landscape opened the land for new plant and animal life to develop.
