After the barrier, turn immediately right (or second right), you can park there.
Then follow the signs towards RØSTIG.

Are you coming in your van or camper? Then after the barrier, drive left towards the RØSTIG gate and park your sleeping spot nicely in your (designated) spot.
Are you coming camping with a tent? You can drop off your stuff at the RØSTIG gate or borrow a trolley (if one is available).
– just as easy.

Even countries start here already 🌿
