Depending on where the traveller goes concerning latitude and time of the year, the experience of contrasting phenomena of the Northern Lights or Midnight Sun can be seen.
Between September and March, it is ideal to view the Northern Lights in Greenland or the Aurora Borealis, which are impressive displays of light within contrast.
In summer, the sun does not completely dip below the horizon- a polar phenomenon known as the midnight sun. The Midnight Sun can be seen for a single day or more weeks depending on where you go. In Ilulissat, for example, the midnight sun appears from mid-May to late July.
