If you are new to Oslo, you probably bought the "Oslo & omegn" Climbing guidebook from Kolsås klatreklubb (Link). Note that a new version will be released in 2021, and the current one does not include all the crags in Oslo. In particular, a few highly beginner friendly crags that are not included are

  • Nedre Sydstup (Kolsås), digital and free guidebook can be found here on the Kolsås klatreklubb website
    Nedre Sydstup dries quite fast, has sun from around noon til sunset and has a lot of friendly bolted routes in lower grades, but also a decent number of interesting routes up to Norwegian grade 8. The rock is a bit loose, so both climber and belayer should wear a helmet! Very convenient to reach with T-bane 3.
  • Den skjulte veggen (up at Kolsåstoppen), digital and free guidebook can be found here https://www.kolsaas.no/klatreforeren-for-oslo. This crag is a bit shaded, so it is very well suited for the summer.
  • Isdammen, free route description can be found in the happy climbers Facebook group (go to "Media" in https://www.facebook.com/groups/happyclimbers). Lots of friendly bolted routes in the lower Norwegian grade range, and thus very popular since its rebolting by Olav Vestlie in 2020. Convenient to reach with the bike!
  • Svaraberget, digital and free guidebook can be found here https://www.kolsaas.no/klatreforeren-for-oslo
  • Skullerud, convenient to reach with T-bane 3. Topo information can be found here: https://www.thecrag.com/climbing/norway/skullerud
  • Megaløkenhavna: Olav Vestlie bolted some new and friendly routes in 2021 there. The rock is a bit loose, so both climber and belayer should wear a helmet! Very convenient to reach with T-bane 3 and bike/15 min walk. Update can be found here: https://m.facebook.com/groups/happyclimbers/permalink/3568638206496066/

Some notable crags which are not in the "Oslo & omegn" guidebook:

  • Hyggen (Drammen). Topo is for example in the highly recommendable guidebook "Climb Norway"


  • The crew behind Gryttr (https://www.gryttr.com/, Gryttr Facebook page) provide an extremely nice service to the climbing community in Oslo: Boulders in østmarka are named and described with grade, picture and sometimes beta videos, and are located on a google maps card, make sure to check it out! They will also release a guidebook for bouldering around Oslo in 2021.
  • There is a public "bouldering wall" in Oslo, just search for "Ammerudtunnelen"



  • We have the book "Sikker klatring" (https://www.friflyt.no/bok/sikker-klatring) in our bouldering room at Blindern, so come by for a good session (after SiO re-opens) and educate yourself in the breaks
  • Do you want to convince your friends to wear a helmet not only when belaying, but also when climbing? Show them a few weekend whipper videos, e.g. here: https://youtu.be/ZkidNWmhSPs
  • Do you climb hard (i.e. risking decent falls?) and your weight is more than ~ 130 % of the belayer's weight? Then you might want to learn about the Edelrid Ohm (see, e.g. here https://www.youtube.com/watch?v=t6ElZtMcvpM) if you care not only about your own, but also your belayer's safety! Of course, rope management becomes a bit more tricky, but some climbers find that its safety benefits outweigh its drawbacks (you can't pull lots of rope very fast when clipping in panic, for example).
  • Did you ever worry about losing your ATC on a multipitch? In such a scenario, it would be good to know how to rappel with a knot called hunters hitch, see for example this video: https://youtu.be/Y1V5Pnc3OuQ



Some ideas that have emerged within some climbing communities over the last decades

  • Is it wet at the bottom of the crag? Put on your shoes on a rock or a rope bag, and try to avoid walking through mud with your climbing shoes, as this will smear the (foot-) holds on the route. It has the benefit retaining the grip of your shoes as well.
  • Are you projecting a route on toprope or putting up a toprope for your friends? In Norway it is favored that you use your own draws/locking carabiners instead of using the rappel rings / rappel bolts. This reduces the wear on the bolts significantly!
