This bicycle tour into the Buck’sche Schweiz heads south from Lake Senftenberger See and is a treat for nature lovers in particular. Cycle through seemingly endless pine forests to Hohenbocka and into the Buck’sche Schweiz. The treasure of the region, its “glass boulders”, lie at the foot of the observation tower. This solidified glass sand forms sandstone boulders in a range of bizarre shapes, making for a natural spectacle that is well worth seeing.Length: 22 kilometresStart/finish: Hosena railway stationLogo/route sign: not specifiedHow to get there:Train: Take the RE2 from Berlin central station (Hauptbahnhof) to Cottbus.
