Even though only the remains of the Storkeegen oak tree can be seen here since a hurricane, it is still impressive. After all, the tree was over 800 years old.

A mountain bike trail called the ‘Devil's Path’ winds its way through Lystrup Forest. It consists of two loops.

Not worth it. There's no forest there anymore (2025), just fallow land, and in my opinion, there are only two boulders off the path, which you can see on every corner in the rest of the forest area...

Translation of the plaque: The Royal Oak is between 1,500 and 2,000 years old. Since the giant has been hollow for centuries, it may have sprouted in the year 0. The Royal Oak was a huge oak tree when Gorm the Old reigned. Around the 16th century, Christian IV carried out the first major oak felling operations [...]. By that time, the Royal Oak was already rotten inside. At the same time, it was inaccessible, and lumberjacks were deterred by its size and gnarled trunk. The Royal Oak [...] is a popular subject for artists (painters). The Royal Oak once had a circumference of 14 meters. [...] Today, only a thin but viable bark remains. New shoots sprout from the old bark from above, forming a new crown.

One of many highlights of Jægerspris alongside the castle. Dismount and wander around the red brick buildings and enjoy the quiet atmosphere. Danner Cafe or the excellent ice cream shop nearby offer a welcome reward.
