Tretstein waterfall, Natural waterfall in Gräfendorf, Germany

Tretstein is a waterfall in Gräfendorf that winds through a gorge carved into Upper Buntsandstone and forms multiple cascades. The water drops roughly three meters freely before striking angled rock formations, reaching a total height of about six meters.

The waterfall formed through the Eidenbach stream's gradual erosion into the region's Buntsandstone rock layers over millennia. In 2010, the Gräfendorf Youth Fire Brigade renovated the access trails, adding handrails and rebuilding wooden walkways.

The name Tretstein is a phonetic contraction of the local dialect word "Trätsch-Stein", which means "splashing stone", referring to the sound of the falling water. The stream is the Eidenbach, and just below the falls it cuts a short gorge-like incision into the Röt beds of the Upper Buntsandstein.

The waterfall lies about two kilometres north-east of Dittlofsroda and one kilometre north of the Eidenbacherhof, in the southernmost Bavarian Rhön. In 2010 the Gräfendorf youth fire brigade renewed the paths: around one hundred metres were secured with a handrail, several wooden walkways replaced and natural steps cut into the slope. The stream continues past further small falls to the Waizenbach.

The waterfall is designated as a natural monument and geotope because it clearly displays the rock layers and erosion processes of the region. Hikers can observe how the force of water continuously works on the sandstone, gradually reshaping its features.
