From the viewing platform we have a beautiful view of the sea of rocks. A legend explains very well how the sea of rocks came into being: When the devil was traveling through the area with a large sack full of stones, the sack scraped past the rocks lying around, creating a hole in it. The further the devil went, the bigger the hole became. Eventually the devil kept losing his rocks from his sack - until the whole sack ripped at this point, creating the sea of rocks.

This is really an adventurous path that is really fun.😁 You can walk all the way to the Oeseteiche. Access from the Edelburg is difficult - you have to look a bit. Some parts are steep, so you need to be sure-footed and not afraid of heights. Not recommended when it's wet.

The Felsenmeer in Hemer, a unique natural monument in the Sauerland, combines natural history and cultural aspects in a fascinating way. The geological formation of this remarkable geotope goes back millions of years and is the result of the weathering of limestone through dissolution processes. Rainwater, enriched with carbon dioxide from the atmosphere, turns into a weak acid that dissolves limestone and thus forms the characteristic rock formations of the Felsenmeer. The impressive landscape forms that are now known as the Felsenmeer were created over geological periods of time. This nature reserve is not only a prime example of the dynamic forces of earth's history, but also a place full of legends. One of the stories is about dwarves who searched for precious metals under the rocks and giants who wanted to steal these treasures. The legendary dwarf king Alberich is said to have caused the ceiling of the rock hall to collapse with a magic spell, burying the giants under the rocks and creating the Felsenmeer. Visitors can explore the Felsenmeer via a variety of paths, including a wooden walkway that leads directly over the cliffs and rocks. There is also a viewing platform and an upper bridge that are barrier-free, so visitors with limited mobility can also enjoy the nature reserve. Dogs are allowed on a leash, and there is a large, free car park at the neighboring Sauerland Park. The Felsenmeer Hemer is a special experience in every season, be it snowy, in the colorful autumn forest, or in the lush green of summer. The cliffs and caves of the Felsenmeer are part of the impressive karst landscape, which visitors can explore in more detail on display boards. Recognition as a "Significant Geological Monument of Germany" and as a "National Geotope" underlines the unique importance of this natural monument and its position as one of Germany's outstanding natural wonders.
