google（見內）可以春秋去。極光強度高才好看，如果在那趕上大爆發就好了，那些tour也是把遊客拉到遠離城市燈光的地方

Iceland is a top destination for viewing the Northern Lights, also known as aurora borealis, due to its open spaces and minimal light pollution. The best time to see them is late September to early April when the nights are long and dark, especially around the equinoxes in September and March. However, sightings have been reported as early as August and as late as April.
