A couple of true hairpins at either end, otherwise more regular - but nice - corners. You gain quite a lot of altitude for the middle part, with a wonderful change of scenery as a consequence. Watch out for sheeps on the loose!
A great alternative to the much more travelled routes between Oslo and
Trondheim (E6 or E3). Basically, a diversion from the E6.
At Ringebu take off up the hill to the East (left).
Soon you are on the naked mountain, with great vistas to behold.
The route passes through a National Park, and has multiple mountain lakes and ponds with plenty fish. There is also lots of wildlife - make sure you dont hit any of them!
One stopping-place in particular is beautiful. Look for the sign for special Sight.
Note: The route is not open all year, but should be for most of the biking-season)
