그레벤하인‬에서 가장 멋진 ‪20‬개의 천연기념물

A small, unassuming, but historic spring on the western slope of the Vogelsberg mountains. This is the source of the Nidda River, which flows for approximately 90 km before passing through Bad Vilbel and Frankfurt. An idyllic spot in the woods, usually quiet and surrounded by mossy greenery – perfect for a short break on your hike. 💧🌲

Beautiful fish pond, great landscape, easy H circular route

From the looks of things, the tower seems to have been left to its own devices... if something doesn't happen soon, it will be demolished... which would be a real shame

Fantastic view from up here… but whether it will be enough for Frankfurt is up to the weather forecasters

One of the more recent volcanic eruptions… now a “hidden block dump”

Once a reservoir for floating wood, then a trout farm and now a nature reserve. An idyllic spot on earth.

Spacious shelter with seating inside and snack area including table outside not far from the Niddaquelle

The Gackerstein geotope near Schotten was created when magma rose and broke through existing rock units. The volcano that once belonged to it no longer exists. The forces of erosion have eroded it to such an extent that only the vent filling remains, which today appears as a dome. The Gackerstein is part of a larger fracture structure that made it possible for the magma to rise through the earth's crust. This structure runs from north to south, so that magma also reached the earth's surface elsewhere, for example the Bilstein near Schotten to the south and the Ulrichstein castle hill.
