Beilstein Trail

Highlight • Trail

Cooler, partly very steep trail that is worth it. The entrance is hard to find (at least currently in autumn), luckily there is an NSG sign at the entrance.

The Beilstein is a large basalt rock. Remains of a former hilltop castle can still be seen on the summit plateau.

There is no cave at Beilstein. It is the remains of an old volcano.

A castle ruin, of which there is not much left to see, but still interesting.

The Beilstein is a basalt cone with the largest basalt cave in the Main-Kinzig district. The formation was formed by volcanic eruptions 10 to 20 million years ago; the surrounding red sandstone, which otherwise characterizes the Spessart, is around 200 million years older. The basalt breach was exposed by erosion; The typical basalt columns and smaller, spherical structures can be seen on the rock walls. On the mountain, which was first mentioned in a document in 1059, are the remains of the small, medieval hilltop castle of Beilstein. It was built to protect the possessions of the archbishopric of Mainz and to control an old road, and was first mentioned in 1343. It was also intended to protect the first glassworks that were established. When rule passed to the Counts of Hanau, the castle probably lost its importance and has since fallen into disrepair. Due to the poor source situation, little is known about the castle. Source: Wikipedia
