We we walked and hitched along the road and the 3rd car stoppen and took 2 of the 3 of us. You Probably can just stand behind the parking lots as well.
Car stoppen even before we put down our backpacks. Nearby arctic circle center with toilets. Opposite on the lake there are 2 nice shelters and camping spots.
Good spot after the supermarket( which is a good place if you want to ask people). Toilets nearby with charging option. Nice place to camp near the bridge.
