Urban skiing in Oslo is magical with the transition from the hectic pulse of the center of Oslo to the peaceful mindfulness of the forest with an infinity of well-made ski tracks. After a short metro ride from the center of Oslo in 10-15 minutes (Metro line 5 to Sognsvann), a paradise of cross-country skiing opens up.
Oslo people are used to meet people in ski gear going straight into the pub from the metro after skiing. Afterski with happy hour beer drinking is a culture in Norway and you can do it in the village ski resort or urban Oslo.
There are official signs that show the ski tracks straight ahead and anyway there are many friendly Norwegians who will help you if you gget lost. The tracks are two-lane, well-groomed with lighting in the evening but if you want to explore or take a short cut then there are also plenty of lakes to ski on.
