Tips from the Community

David Howells
June 23, 2026, Sti Fra Ullevålseter Til Skjennungstua

This 2.1-kilometre gravelled trail between Ullevålseter and Skjennungstua is a short but super scenic section that meanders through beautiful woodlands. It is also a pretty family-friendly flat trail with only around forty metres of height gain in the entire two kilometres.

A thrilling suspension bridge hidden deep in Nordmarka, just above the roaring waters of Bjørnsjøhelvete gorge. The crossing is short but impressive, surrounded by dense pine forest and echoing with the sound of the river far below.
