Berlin, Liepnitzsee, and Barnim Nature Park Loop

This route is rated as a "hard gravel ride" by komoot, requiring very good fitness. It corresponds to an STS (Single Track Scale) rating of S3-S6, meaning advanced riding skills are necessary. Be prepared for portions where you might need to dismount and push your bike.

The trail features a mixed terrain typical of the Brandenburg region. You'll encounter significant portions of paved asphalt (around 79%), compacted gravel (around 12.3 km), unpaved surfaces (about 16.8 km), and singletrack sections (approximately 11.0 km). Expect dusty double tracks, sandy sections, and even some cobblestones. Some areas, especially near the lake, can be muddy after rain.

The stunning Liepnitzsee, with its clear, often turquoise waters and forested island, is a major draw. You'll also pass the small bathing spot at Wandlitzsee. Other notable sections include the Muddy Path Through Karower Teiche, the Lanker Weg Cycle Path, and Wooden Bridges and Streams in Tegeler Fließtal.
