Meeting point: Jernbanetorget / Oslo main train station (Map)
Europarådets Plass between Byporten and Arkaden shopping centers, outside Rica Hotel Oslo. You’ll see a big yellow wall with a sculpture on it, and below a fountain with a curb in front. See you there! Take any subway to the main train station.
For those arriving from out of town, here’s some useful links regarding a place to stay.
Sleeping in the city
Keep in mind that camping is free in Norway, as long as you’re more than 150m from private property, this could get tricky if you’re trying to stay close to town. The islands are quite close but the tricky bit here is getting to and from town in the evening/night.
