Every traveler’s life list should include viewing the Northern Lights, or Aurora Borealis, one of nature’s most spectacular phenomena. From late November to March within the Northern Lights zone—latitudes 65 to 72 degrees—solar particles collide with atmospheric gases to create colorful curtains (near the South Pole, Aurora Australis are the Southern Lights). Ideal viewing conditions are crisp, cold, clear, and cloudless skies with little light. You can see this most impressive light show—lasting from a few minutes to several days—in the following regions close to the Arctic. Here is a list of the best places to go to see these captivating lights.
