If you have never been in Northern Scandinavia during the midsummer period, the bright nights are perhaps the most fascinating and apparent phenomenon. The sun doesn’t set at all. You can get spectacular views of the surroundings from the city mountain, Luossavaara, about 4 km outside Kiruna. The midnight sun can be experienced between 27 May and 14 July in Kiruna.

2009 saw Gamcheon turn from an area of budget housing for refugees of the Korean War into a premier tourist attraction, all thanks to a collective effort by local students and artists, who transformed the neighbourhood with colourful wall painting and street art. Today Gamcheon even has a tourist office of its own: stop by on your way in to pick up a detailed map of the village's attractions; collect a stamp at each and you'll receive a small prize from the tourist office on submission. There is a small museum telling the neighbourhood's story, and a number of shops, cafes and street food stalls. When wandering the maze of Gamcheon's streets, please respect the privacy of family homes.
