The trip across the Vidden is well known, and with good reason! Close to the city you can experience real high mountains at all times of the year, easily accessible with Ulriken cable car. Set aside plenty of time to enjoy nature and these great views. The trip is also great on skis when there is snow.
Perhaps you can start at mount Fløyen and end up at Mount Ulriken, then you can plan to enjoy at wondering meal at Skyskraperen restaurant.
The hike is about 13 kilometers from Ulriken to Fløyen, and you usually spend about four hours.
If you take the cable car up / down, the time is shortened by about an hour.
