Behl-Benz-Kaköhl-Hohwacht-Rantzau

-you can almost always ride on the road

-shortly before Sieversdorf, there is a long descent. unfortunately, you have to brake before the village street

-behind Benz, the asphalt is poor

-use the bike path on the L178

-behind Kaköhl, there is no bike path from the Sehlendorf junction, so you have to push through to Hohwacht (first downhill, then longer uphill)

-in Kembs, there is a curve of about 160 degrees

-behind Emkendorf, there is a steep ramp

-on L165, use the bike path again

-before Rantzau, the road is partly just for tractors (good asphalt), turn right in the descent before the B430

-and then just back on the bike path to Plön

-it should all be well signposted in the villages, just have to be careful ;)
