There are many ways to potentially see the Northern Lights, from trekking the tundra to floating in a secret lagoon to flying all the way to space. But none of these are guaranteed, as it must be precisely the right time of year -- in precisely the right location -- for travelers to catch this fickle light show at its best.
Thank the starry heavens for a plane that lets you see the Northern Lights ALL the time.
Icelandair's new jet, the Hekla Aurora, hosts a constant light show in the cabin no matter the time of year or the weather. It’s all thanks to technicolor LED lights that flash a “Northern Lights” glow right over passengers’ heads.
And while we’d love to see the real thing one day, this makes a pretty spectacular stand-in.
The Hekla Aurora currently flies all around Icelandair’s routes, making stops everywhere from Boston to Oslo to Copenhagen. You can check online to see which routes the jet will fly next.

Why Go: Alaska's location within "the zone" means you're almost guaranteed to see spectacular light displays. Be sure to move further away from city lights of Fairbanks into the region's vast wilderness areas of Denali and the Yukon Territory.
Insider Tip: Check the University of Alaska's Northern Lights forecast to help schedule your viewing trip.
Best Viewing Locations: Anchorage, Fairbanks, Denali

Why Go: North of Scotland between the Norwegian Sea and the North Atlantic, the Faroe Island archipelago is mostly known for puffins and Viking folklore. While its stormy weather mimics that of the British Isles, visitors to this Denmark-owned province could also see the iridescent lights.
Best Viewing Locations: All islands within its archipelago

Why Go: The British isles are known for stormy, foggy, and cloudy weather--far from ideal conditions for observing the sky, but on those rare occasions when thick cloud covers break momentarily during dark winter months, you've got a good chance of witnessing the display in parts of Scotland's north.
Best Viewing Locations: Aberdeen, Isle of Skye, Northern Highlands, Dunnet Head

Why Go: Areas around pristine Lake Superior in Ontario and Northern Canada's tundra back-country are prime viewing spots. Head to the town of Whitehorse within the Yukon Territory to best see the swirling lights. Sometimes, the glowing sky can be seen as far south as the American border, but stick to Canada's vast wilderness for your front row seats.

Why Go: Greenland still remains a final frontier for the average traveler and from its interior ice remains optimal location, however more accessible areas south and east of Greenland provide just as good viewing opportunities. You can see northern lights from most parts of the country (similar to Iceland).
Best Viewing Locations: Kulusuk, Ammassalik

Why Go: Head to Luosto in Northern Finland to the Aurora Chalet where, upon arrival, you'll be handed an "Aurora Alarm" which beeps once Northern Lights appear. In the nearby town of Sodanklya, the Northern Lights Research Center relays your message via the hotel. On chilly cloudless nights, you're also bound to catch the lights shimmer in the skies over the town of Nellim, close to Lake Inari--Finland's third largest lake.
Best Viewing Locations: Luosto, Nellim, Utsjoki,Ivalo, Kakslauttanen

Why Go: Leave the bustling nightlife of the capital city and head out into the wide open plains of Þingvellir National Park--a UNESCO Heritage Site where the North American and Eurasian continental plates meet to cause a rift valley. Under clear dark skies on a freezing night in early March was where I first witnessed the lights dance across the Icelandic sky. Though the show only lasted for 12-15 minutes, it felt like an hour.
Best Viewing Locations: Outside Reykjavik, Þingvellir National Park, the entire country.

Why Go: The area around Abisko in Swedish Lapland is scientifically proven to be an ideal viewing spot due to a unique micro-climate. Close to Abisko National Park, the dark winter night is perfect for sky watching. The 70km (43mi) long lake helps create the infamous "blue hole of Abisko"--a patch of sky that remains clear regardless of the surrounding weather patterns.
Best Viewing Locations: Kiruna, Abisko, Swedish Lapland

Why Go: In Northern Russia, you've got a good chance of seeing Aurora Borealis. The Kola Peninsula's proximity to the Northern Lights zone also makes it a key area and the town of Murmansk is a popular base . . . if you can handle the below freezing temperatures of a typical Siberian winter.
Best Viewing Locations: Murmansk, Siberia, Kola Peninsula

Why Go: The northern town of Tromsø teems with Aurora Borealis activity when those extended summer days are long gone. Its location above the Arctic Circle, and within the Northern Lights zone, makes it one of the top places to view shimmering green lights. The town also boasts the world's most northerly university, brewery, and planetarium. You can cruise Norway's fjord-lined coast aboard a Hurtigruten ship and get wake-up calls to head out on the deck when the lights appear.
Best Viewing Locations: Tromsø, Alta, Svalbard, Finnmark
