ウプフーズムの天然記念物・トップ10

A beautiful raised bog that has been protected since 1968: https://umweltanwendungen.schleswig-holstein.de/Bestellsysteme/pdf/bis_faltblaetter/5413_schwansmoor_und_kranichmoor.pdf

A very fine viewing and resting place

The Schwansmoor and the much smaller Kranichmoor are two protected moorland areas near Süderlügum, covering a total of 84 hectares. Peat was previously mined here, but was subsequently renaturalized. The area has been a nature reserve since 1968. The moorland itself is not accessible; it is completely surrounded by forest.

Also worth seeing in winter.

The Süderlügum inland dunes (Danish Sønder Løgum Klit) are a nature reserve in the Schleswig-Holstein municipality of Süderlügum in the district of North Friesland. https://de.wikipedia.org/wiki/S%C3%BCderl%C3%BCgumer_Binnend%C3%BCnen

"In the middle of the countryside" is no great surprise. To the west of Süderlügum there is almost exclusively reclaimed land. I once read that 100 years ago you could take a boat from Aventoft to Leck. Lecker used to be a port town (Lecker Au). This is a wonderful path to the Ladelund concentration camp memorial and meeting place. The path roughly corresponds to the route of the anti-tank ditch that forced laborers wanted to dig over 13 km to Humptrup. The meeting place was beautifully redesigned in 2018 and contains information for various ways of dealing with the topic. By the way, it is also very nice to drive to the Schwesing memorial on the Geest. I have already done that myself. The Kolkerheide near Löwenstedt is similar to the landscape near Süderlügum.

Of course you should stay on the paths! ... otherwise there will soon be a sign: MTB ride forbidden ... and the people with it their dogs are happy, they run there often without a leash!
