It might be a little difficult to navigate around Klippan, but it might be less questions if You use this map. Observe that there is two villages with the name Sönnarslöv in this area.

After leaving Rd 21, just follow the road. If You don't take the wrong way after V Sönnarslöv and end up in Krika, You will now find a nice road winding up through dense forrests up the Söderåsen (South Ridge).
