Røverkollen is a 404-meter-high hill located on the border between Oslo and Nittedal municipalities, featuring a prominent TV mast and a concrete lookout tower. The area is ecologically valuable due to its unique limestone pine forest and diverse vegetation, and it includes old burial cairns and historical significance as a site linked to ancient road robbers; part of it has been protected as Røverkollen Nature Reserve since 1993.
