Drive road 35 towards Jevnaker, from south. After you have passed Jevnaker centre, you will soon pass Hadeland Glassverk on your right hand side. Proceed another 300 metres and turn left immediately after you have driven under a railway bridge. Drive 500 metres and turn right where signed for "Gjerdingen" and "Tverrsjøen". This is just before an XY petrol station (per August 2010), and the road is called Svenåvegen. Follow this road 6.9 km to a large car park on the left hand side of the road, just before some buildings. Note that you need to pay toll (NOK 40 by August 2010) 500 metres after starting on Svenåvegen.
From the car park walk downhill around the buildings, and head left when you get down to the lake. The forest road now turns right, and you should fork left onto a soil forest road when you see a sign for "Svarttjernshøgda". This, partially boggy, forest road runs parallel with the more major forest road that runs along the lake. Follow the forest road approximately 70 metres and then turn left onto a path, marked with white and blue paint on wooden poles. After approximately 250 metres the path marked with white paint forks left, and you should follow this path. This path can be followed all the way to the summit, which has an 8 metres high wooden tower. Up here you will find a registration book.
Descend by reversing your ascent route.

We left Nesbyen early this Saturday morning, and after some sightseeing we headed to Jevnaker, where Elisabeth paid a visit to Hadeland Glassverk while I drove up to Tverrsjøen to hike Svarttjennshøgda. The weather was quite grey, and there was light rain when I headed out from Tverrsjøhytta.
Finding the path to Svarttjennshøgda was quite easy, but when I got to the path junction in the forest, where the white and blue paths diverge, I decided to stay on the blue path since the sign for Svarttjennshøgda down by the forest road had blue paint. My gut feeling told me that staying on the blue path wasn't quite right, but I assumed consistency in colours used to mark the paths. But when I met the forest road I had been driving up from Jevnaker I understood for sure that I had been heading the wrong way. So I turned around and followed the white path when I got back to the path junction.
The path I was now following was extremely wet and boggy, and it was topped by me stepping into a two feet deep mud-hole. After this there was no point trying to stay dry, and I proceeded through the forest all the way to the summit. I was a bit surprised to find a view tower at the summit, but was happy to climb this in order to get a view of the area. Unfortunately the clouds restricted me from seeing very far.
After the summit view I headed back down to the car, including another de-tour
when I missed my correct route in a path junction. Back at the car I changed
into dry clothes and drove down to Hadeland Glassverk to pick up Elisabeth. From
here we drove to Kongsberg for Halvard's 50th.
