One of the highest elevations, and a popular viewing point in the nature park, is the Haußelberg at 119.1 metres above NN. There are still a few intact raised bogs, notably the Bornrieth Moor near Oldendorf, but also the small bogs near Hetendorf and Müden/Örtze, that have colonies of protected plants like the sundew, the bog-asphodel, the bistort and the cottongrass, as well as rare orchids like the Western marsh orchid, das heath spotted orchid, the lesser butterfly orchid and the Broad-leaved Helleborine.
