The waterfall grows in length because the calcifying moss traps calcium carbonate from the spring water.
The site was declared a natural monument in 1938 due to its unique geological formation.
It is one of the few places in Germany where active tufa formation is clearly visible and ongoing.
The water originates from three separate limestone springs located slightly uphill from the main cascade.
The waterfall is technically growing 'into' the valley, shifting its position over decades.
The tufa rock is extremely fragile and protected under environmental law, prohibiting climbing or trampling.
The Dreimühlen-Wasserfall is a unique petrifying waterfall located in the Eifel region of Germany, officially designated as a natural monument. It is formed by the constant deposition of sinter lime from three cold-water springs, which causes the moss-covered rock formation to grow by a few centimeters each year. The waterfall is situated within the Ahbach valley, surrounded by wooded trails and expansive meadow landscapes. Unlike traditional waterfalls, this feature is created through a chemical-biological process where spring water with high calcium bicarbonate content loses carbon dioxide, resulting in lime precipitation. Visitors can observe the porous tufa rock structure that extends several meters into the surrounding stream bed. The site serves as an important habitat for rare moss species that thrive in the calcium-rich environment. It remains accessible via local hiking trails that connect the surrounding rural villages.

Wear sturdy, waterproof hiking boots, as the path near the stream can be muddy and slippery.
Stay strictly on the marked boardwalks and paths to protect the delicate moss and sinter formations.
Bring a camera with a macro lens to capture the unique texture of the calcified moss and water patterns.
Do not attempt to climb the waterfall structure for photos; the tufa is brittle and legally protected.
Do not touch or walk on the sinter rock; keep dogs on a leash to protect the sensitive ecosystem.
