The 'Muskau Arch' is the only geological structure of its kind in the world that can be clearly identified from satellite imagery.
The park's signature colorful lakes are the result of flooded post-mining excavations that became acidic due to pyrite oxidation.
The moraine arc is approximately 40 kilometers long and spans both sides of the Neisse River.
Geologically, the arch was formed when glacier pressure shoved subterranean rock layers into a horseshoe shape.
The park contains highly acidic lakes with pH levels sometimes reaching as low as 3.0.
It is designated as a UNESCO Global Geopark, recognizing its status as a site of international geological significance.
Park Krajobrazowy Łuk Mużakowa (Muskau Arch Landscape Park) is a UNESCO Global Geopark featuring a unique horseshoe-shaped terminal moraine formed during the Saalian glaciation. The landscape is defined by former open-cast lignite mining sites that have transformed into colorful anthropogenic lakes. These bodies of water range in color from turquoise to deep red due to varying chemical compositions, iron compounds, and high mineral content. The park spans the border between Poland and Germany, physically linked to the Muskauer Park/Park Mużakowski. Visitors can explore the 5-kilometer geotourist trail, which includes a wooden observation bridge and stairs leading to mining pits. The terrain is largely forested, hiding relics of 19th-century industrial mining infrastructure. This area is legally protected to preserve its significant geological formation and biodiversity. It remains an active site for geological research while functioning as a recreation area.
The wooden observation platform overlooking the 'Turkusowe Jezioro' (Turquoise Lake).
Bring a good pair of hiking boots, as the path around the flooded mining pits involves uneven terrain and steep wooden staircases.
Visit the 'Africana' viewing point for the best perspective of the most vibrant turquoise lakes.
Carry drinking water and snacks, as there are no food vendors within the central geological trail area.
Do not attempt to swim in the lakes; the water is highly acidic and hazardous to skin and health.
Stay on marked trails to protect fragile post-mining vegetation and avoid the unstable, steep edges of the mining pits.
