On many travelers' lists of things to do before they die，you'll find "See the northern lights" written down.Rightfully so-these lights are one of nature's most jaw-dropping views.
   In Sweden，the northern lights usually appear from late March or early April.Your best chance of catching a glimpse of them is on cold winter nights when the sky is clear，dark with little to no moonlight，and cloudless.You need to be away from city lights and go to the countryside.For those willing to brave the cold on winter nights，here are some of the best locations.
   Abisko National Park
   Abisko National Park is a main location.The scientifically confirmed "blue hole"-a piece of sky over the Tornetrask lake that usually remains clear despite cloudy weather nearby一 gives Abisko its own microclimate（局部地區(qū)氣候），which is suitable for catching the lights.
   Jukkasjarvi
   The village of Jukkasjarvi only has about 550 people.But don't let the small population size fool you：Jukkasjarvi owns the world's first ice hotel and is one of the best places to view the northern lights.The ice hotel organizes guided tours for guests to the Esrange Space Center.There you can eat at a camp outside and see the Arctic winter sky for aurora borealis（北極光）.Or why not try to get closer to the northern lights and watch them through an aeroplane window？The ice hotel arranges flights for the amazing northern lights experience.
   Gallivare
   You can drive a snowmobile to the mountain top in Gallivare for a private light show，or head a few kilometers to nearby villages to watch those lights shining across the dark winter sky.But remember-if you do get the chance to see the northern lights in person，never whistle to them.According to ancient Sumi fairy，it brings you bad luck.
