🚗 Driving 🚗
Parking is limited, public transport recommended. Public parking available near Hellerudsvingen 28, 0684 Oslo (59.899910, 10.851864). From Oslo city centre take Rv162, E6, Tvetenveien and Hellerudveien to Hellerudsvingen in Bydel Østensjø. Takes about 15 minutes. Alternative, limited street parking is available on the north side of the area, near Trollåsveien 45, 0672 Oslo (59.907261, 10.856318). This makes for a longer approach to the deluxe sector, but is a good way to combine it with the Lia crag.

🚶♀️ Approach 🚶♂️
Good gravel path from parking lot. Follow path eastwards, into the forest. The first boulder (Åsynsteinen) is visible from the path on the right side after about 8 min of walking. From this point (and the next 400 meters of gravel path) you can branch off to the south onto trails (use the map).
To get to the boulders in the eastern parts, follow the gravel path to a wide intersection, make a right, and follow the path to a small lake. From here you are close to the boulders in Sveitserparken, or can find the main trails that will lead you to Lutsteinen, Edelsteinen and Lut i skogen.
