We drove from Holmestrand towards Oslo on E18 and took off towards Sande. We took the first road on the right after the roundabout and then headed in towards Hvittingen. The road was not in great condition and I wouldn't have risked my car on it, but my friend was willing to take hers up there, so who am I to complain? We parked just before a little lake and walked the rest of the way up the road to the top. It was actually possible to drive the whole way for those with good suspension. There was a fire-tower on the top and good views around the district. It took about 1 1/2 hours up and down.
