Northern Lights: All You Need to Know

October 08, 2025 5 min read.

Traveling is an exciting experience for most people. Many dream of visiting exotic destinations, relaxing at beachfront resorts, or exploring quiet, beautiful mountains. However, there are travelers who like to go one step further and seek out unique natural phenomena in the world, even if it means adapting to specific seasons or traveling to remote regions to witness them. Such is the case of the breathtaking Northern Lights.

What are the Northern Lights?

In scientific terms, the Northern Lights are a natural phenomenon: a display of dancing lights in the night sky, mainly visible at high latitudes in the Northern Hemisphere. They occur when charged particles from the Sun (solar wind) collide with the Earth’s upper atmosphere.

For travelers, it’s like watching a movie-like spectacle, where the sky lights up in shades of green, violet, red, and blue. Very few people are lucky enough to witness it in person, which makes it an unforgettable experience.

Where to See the Northern Lights?

The Northern Lights are not only a natural wonder but also a growing tourist attraction. Whether to experience a magical moment, propose under the illuminated sky, or simply capture unique photographs, more and more travelers set out each year to see this phenomenon.

The Northern Lights are mainly observed in the Arctic Circle and nearby regions, where dark skies and low light pollution create ideal conditions. Here are the top destinations:

🏔️ Norway

Tromsø: Known as the capital of the Northern Lights, with specialized tours, glass-roofed cabins, and vibrant city life.
Lofoten Islands: Dramatic mountains and fjords that make the spectacle even more photogenic.
North Cape (Nordkapp): The northernmost point of Europe, perfect for adventurous travelers.

Travel tip: Norway has excellent winter flight connections, and many tours offer “aurora chasing” in minibuses to escape the clouds.

🎶 Sweden

Abisko: Famous for its “blue hole,” a microclimate that keeps skies clear even in winter. Home to the Aurora Sky Station, one of the world’s best viewing spots with expert guides.

Extra tip: Abisko is especially popular among professional photographers due to its high number of clear nights.

🦌 Finland

Finnish Lapland (Rovaniemi, Saariselkä, Kakslauttanen): Sleep in glass igloos or Nordic cabins and watch the lights from your bed.
Kittilä and Levi: Combine skiing with aurora experiences.

Good to know: In Finland, the Northern Lights can be seen up to 200 nights per year.

🌋 Iceland

Reykjavik: Although the capital has some light pollution, you can find dark skies with a short drive.
Vik and Akureyri: Smaller towns surrounded by nature and mountains.

Extra tip: Iceland lets you combine auroras with waterfalls, volcanoes, and geysers.

🍁 Canada

Yukon and Whitehorse: Vast snowy landscapes with strong tourist infrastructure.
Northwest Territories (Yellowknife): Recognized as one of the best places in the world, thanks to its clear skies and long aurora season.
Nunavut: Remote but with pristine skies and stunning views.

Travel tip: Many Canadian programs include heated cabins and dog-sled excursions.

☃️ Alaska (USA)

Fairbanks: The epicenter of the auroras in the U.S., with more than 200 nights a year of visibility. Also home to the Aurora Ice Museum, which combines cultural experiences with nighttime viewing.

When to See the Northern Lights?

Best time of year: September to April, when nights are longer and darker. Peak visibility is between October and March, coinciding with the Arctic winter.
Best time of night: Usually between 10:00 p.m. and 2:00 a.m., though they can appear anytime at night if solar activity is strong.
Weather conditions: Clear skies and low light pollution are essential. Rural areas far from cities offer the best views.
Additional factors: During periods of high solar activity (about every 11 years in the solar cycle), auroras can be more intense and even visible at lower latitudes.
Summer in the Arctic: Between June and August, sightings are nearly impossible due to the midnight sun, which keeps the sky bright even at night.

How to Increase Your Chances of Seeing the Northern Lights

Get away from cities and artificial lights: choose rural areas or natural parks.
Check aurora forecasts: websites and apps like Aurora Forecast or My Aurora Forecast track real-time solar activity.
Stay several nights: even in the best places, there’s no guarantee. Staying 3–4 nights increases your chances.
Wear proper clothing: thermal layers, boots, gloves, and gear for extreme cold (-10° to -30°C in winter).
Join specialized tours: in Tromsø, Abisko, Iceland, or Fairbanks, guided excursions take you to the best viewing spots.
