The 'Babina' mine operated from 1920 until 1973, leaving behind deep scars in the landscape now occupied by acidic post-mining lakes.
The high acidity of the water in some reservoirs—sometimes reaching a pH of 3—is caused by the oxidation of pyrite found in the local lignite and clay deposits.
The Muskau Arch, where the park is located, is a massive terminal moraine formed by a glacier pushing up subterranean material during the Pleistocene.
The trail features a wooden observation tower that provides a panoramic view of the flooded mining pits and the surrounding forest canopy.
Several reservoirs exhibit vibrant colors, ranging from intense turquoise to deep brown, depending on the mineral content and depth of the basin.
Ścieżka Geoturystyczna „Dawna Kopalnia Babina” is a 5-kilometer educational trail located within the Muskau Arch UNESCO Global Geopark. The site showcases the post-industrial landscape of a former open-pit lignite mine, featuring highly acidic, colorful water reservoirs resulting from chemical reactions with iron compounds. The trail connects twelve educational stops detailing regional geology, mining history, and environmental reclamation efforts. Visitors navigate through a forest setting where terrain deformations and landslides are visible remnants of historical exploitation. Wooden viewing platforms and bridges provide access to the most significant geological outcrops. The area serves as a primary example of successful landscape remediation in a complex mining basin. It is situated on the border between Poland and Germany, integrated into the transboundary landscape park.
The viewing platform overlooking the largest and most brightly colored acidic lake near the middle section of the trail.
Wear sturdy, closed-toe hiking footwear, as the terrain consists of sandy paths and uneven ground.
Bring binoculars for birdwatching and to better inspect the geological layers on the far banks of the flooded pits.
Download the digital map or trail guide before entering, as mobile network coverage can be inconsistent in deeper parts of the basin.
Do not attempt to walk down the steep, sandy cliffs surrounding the reservoirs, as they are prone to unexpected landslides.
Stay strictly on the marked paths to protect fragile, regenerating soil; swimming in the acidic lakes is strictly prohibited.
