In case you try to use a ramp from Cologne, a good take-off sign is Remscheid, because the first service area on the [[A1 (Germany)|A1]] is Rasthof Remscheid, just before the exit for Remscheid. There are lots of commuters. You can also get there by train from Cologne Dom/Hbf for 6,50 Euros via Remscheid Hbf and walk 5 km to the area (map [http://maps.google.com/maps?f=d&source=s_d&saddr=Remscheid+Hbf&daddr=Unknown+road&hl=en&geocode=FTLnDAMdiNttAClRpZsmWyq5RzGlIfHuvHkWrQ%3BFayeDAMdfEduAA&mra=dme&mrcr=0&mrsp=1&sz=15&dirflg=w&sll=51.157143,7.226601&sspn=0.008559,0.023174&ie=UTF8&ll=51.169872,7.215099&spn=0.034228,0.092697&t=h&z=13 here]). If you're lucky, catch the bus 672 or 673 (valid with your zone 4 ticket) to Talsperre/Mebusmühle or Talsperre/Raststätte (closer but only 673) and avoid the walk. These buses do not pass very often, though.
