The "Fledermaustunnel" as part of the SauerlandRadring and Ruhr-Sieg-Radweg between Finnentrop-Fehrenbracht and Eslohe-Kückelheim is closed annually at the end of October.
After that, the animals from which the Kückelheim tunnel gets its name can move back into the 689m long tube to hibernate there undisturbed for a good five months.
At the latest on the first weekend in April, the new cycling season can begin again. With favorable climatic data an earlier opening is also possible. We will inform you about the exact date in time.
For cyclists who want to ride the SauerlandRadring or the Ruhr-Sieg-Radweg on the route Finnentrop - Eslohe also in winter, a winter bypass from Fehrenbracht via Schliprüthen, Obersalwey, Niedersalwey to Eslohe or the other way round from Eslohe via Niedersalwey, Obersalwey, Schliprüthen to Fehrenbracht is signposted as part of the state-wide cycle path network.
The SauerlandRadring can therefore also be traveled via this - albeit topographically more challenging - alternative route during the tunnel's closure period. To do so, follow the junction system with the sequence 42-54-55 from Eslohe or 55-54-42 from Finnentrop.
