Sackberg Summit View

Highlight • Summit

At 411m above sea level, the Sackberg is the highest peak in the Ahlsburg. In addition to a geodetic point, a marker stone and a cairn, you can enjoy the beautiful view on both sides of the approx. 10km long Ahlsburg. You can also be happy to have made it up here at all, because the few access routes are so little developed that climbing the "Top of Ahlsburg" is no child's play.

Dawn Redwood Natural Monument

An impressive tree with a natural monument plaque.

It's good that it's marked, otherwise it wouldn't be so easy to spot. 😉
