The Blies is the most significant tributary of the Saar in terms of water volume, flowing through southeastern Saarland and parts of Lorraine. Over a total length of about 99 kilometers, it traverses the UNESCO Bliesgau Biosphere Reserve, renowned for its extraordinary biodiversity and gentle rolling landscape. The Blies originates in northern Saarland near Selbach and finally flows into the Saar at Sarreguemines. Ecologically, the river's course is of central importance, as the preserved floodplains offer valuable sanctuaries for endangered animal species such as the kingfisher and the black stork. Historically, the water power of the Blies was intensively utilized for milling and later for the burgeoning industries. Today, the river is a popular destination for nature tourists, paddlers, and cyclists using the Glan-Blies cycle path. Along its banks lie historically significant places like Neunkirchen, Homburg, and Blieskastel, which are closely connected to the river's path. The Blies is thus a defining element for nature and culture in the Saarpfalz region.

🧭

Getting there

The banks of Blies can usually be reached via local rural roads or established cycle paths that follow the watercourse. Public transport often connects the larger towns situated along its meandering route.

Terrain & paths

The terrain along Blies is generally flat or gently rolling, featuring a mix of paved trails, dirt paths, and natural floodplains. Some sections may be uneven, muddy, or overgrown with dense riparian vegetation.
