The summit top of Røverkollen is a stunning location. At the top of this 404-metre-high hill, which sits on the Oslo and Nittedal border, are two great attractions. There is a substantial concrete lookout tower and Bronze Age burial mounds. From the top of the tower you have great views down, overlooking Oslo, Nittedal, and the Oslofjord. For these reasons, it is a popular hiking and mountain biking destination.
