Situated 250 km north of the Arctic Circle this quaint village, Abisko, is considered the perfect location to watch the Northern Lights. However, Abisko is also home to another natural wonder. Known as the ‘blue hole’, a patch of sky which extends from 10 to 20 sq km remains clear irrespective of the weather condition in the rest of the village. The site has attracted several tourists and photographers from all around the world to witness the rare phenomenon.
