[1] It forms part of the Weser Uplands in Lower Saxony southwest of Hanover and north of Hamelin.

The southeastern part of the Süntel, including the Hohe Egge, consists mainly of Wealden sandstone from the Lower Cretaceous period as well as small anthracite deposits.

Its northwestern part, including the Hohenstein with its 350 m long and 50 to 60 m high crags, comprises limestone of the Upper Jurassic period, the Corallian oolith.

In addition there are numerous, rare species of flower such as varieties of Primula, spring snowflake, horseshoe vetch, hart's-tongue fern, spleenwort, lady's slipper, heath spotted orchid, etc.

In the Süntel, as well as hiking trails with views over the valleys, there are also long, straight, rather monotonous forest tracks without any signs.
