This is a nice piece of road. Narrow but not difficult. The surface is mostly good (only a few potholes here and there). Not a lot of traffic, but still be careful in the blind corners. Take a break at the first corner on the top going down Brekkhusfjellet towards Evanger (60.746045, 6.139131), there is a nice table made from natural stone with a beautiful view.
The Bergsdal road takes you up in the mountains on the old road between Bergen and Voss. The area has farms, summer houses and the occasional old power station. Beware of cows, sheep, potholes and blind corners. This is not a good speed run, but a relaxed scenic ride. The scenery is absolutely beautiful, the road is fun to ride and the local bulls are mostly harmless.
