If you start your journey at Ringebu and head north there are a few nice routes you can take. This is just another one that goes through the Fv385 and continues through 3.
In the first part you'll encounter the best corners and the most beautiful landscape. Remember to stop and enjoy the views. I was driving alone most of the time and I could enjoy all these open corners with lots of visibility. There are a few things to watch out, though: In the highest part the road is not in a perfect condition, so you have to be a bit careful; also be very careful with sheep (or other animals) crossing the road.
The second part, along the road 3 there are lots of straights and the road is in perfect condition. Here there are also a few points where you can stop for sightseeing. You'll see a few speed cameras along this road.
