Majestic woodland views. There’s also an outlook post up ahead if you feel like getting a bird’s-eye view of it all.

Very nice gravel hard pack, best consumed on a gravel rig but also enjoyable on a mountain bike.

From the observation tower you have a 360-degree panoramic view, with forests and rolling hills in all directions. On the horizon you will find landmarks such as the towers at Røverkollen and Tryvannshøgda in Oslo and Viktjernåsen in Trøgstad, the radar dome at Haukåsen, the characteristic Kolsåstoppene and not least the twinkling Mosjøen which is right nearby.

After the climb, you can take a breather on the stone and plateau-like open space and enjoy the great view.

Supposedly this is one of Norway’s largest pump tracks. Also, this place has a collection of jump lines, drops and other features. Not too many of these places in the Oslo area, so this is a rare gem!

I don't know who suggested this stretch... komoot or did I choose it that way? If you want to travel here with your bike and luggage, you should have tires with good grip and steel calves for the 12% incline on the gravel path. Otherwise there is only sliding. Unfortunately I didn't have the air for a photo. 😁
