What Are the Northern Lights?
The northern lights, also called aurora borealis, are natural light displays caused by interactions between solar wind and Earth’s atmosphere. When electrically charged particles from the sun collide with oxygen and nitrogen gases, they produce dancing curtains of light across the night sky.
Aurora borealis displays appear in various colors depending on atmospheric conditions:
- Green: Most common, caused by oxygen at lower altitudes (60-150 miles)
- Pink/Red: Oxygen at higher altitudes (150+ miles)
- Blue/Purple: Nitrogen particles
- Yellow: Mix of red and green light
In Fairbanks, northern lights displays range from faint green glows on the horizon to spectacular multi-colored curtains covering the entire sky. Strong geomagnetic storms produce the most vivid displays, with aurora activity measured on the Kp index scale from 0 (quiet) to 9 (extreme).
The best northern lights viewing occurs during dark, clear nights between 10:00 PM and 2:00 AM when geomagnetic activity typically peaks. Our Fairbanks aurora tours are timed to maximize viewing during these optimal hours.
Northern Lights Tours Frequently Asked Questions
What’s the difference between your aurora tours?
Each Fairbanks aurora tour offers a different experience: Chena Hot Springs combines hot springs + aurora, Arctic Circle adds bucket-list adventure, Aurora Lodge prioritizes comfort, and Murphy Dome focuses on photography. All tours include northern lights viewing opportunities, though sightings cannot be guaranteed as this is a natural phenomenon.
What should I wear on a northern lights tour?
Dress for extreme cold: insulated winter jacket, thermal base layers, warm hat covering ears, insulated gloves/mittens, winter boots, and hand/toe warmers. Temperatures during Fairbanks aurora tours range from 20°F to -40°F depending on month. We recommend layering so you can adjust.
Can I photograph the northern lights?
Yes! Bring a camera with manual settings if possible. Smartphones with night mode can capture bright aurora displays. Tripods are helpful but not required. Cold temperatures drain batteries quickly, so packing an extra charger is recommended.
What if northern lights don’t appear?
Aurora borealis is a natural phenomenon and cannot be guaranteed. However, our tours provide value beyond aurora viewing: Chena Hot Springs offers hot springs and Ice Museum, Arctic Circle provides wilderness adventure and a certificate of achievement, Aurora Lodge delivers warm comfort. We do not offer refunds for low aurora activity as this is nature-dependent.
Do you cancel tours for weather?
Tours operate in most weather conditions. Heavy snow, dangerous road conditions, or extreme cold may result in cancellation with full refund or reschedule offered. Cloudy skies alone do not cancel tours – clouds can clear, and aurora can appear through breaks. We also offer a 24-hour cancellation policy.
Which tour is best for photography?
Murphy Dome offers the best dedicated aurora photography experience with 360-degree views and focused viewing time. However, all tours provide photography opportunities. Serious photographers often book multiple nights to maximize chances of capturing strong displays.
How far in advance should I book?
Fairbanks northern lights tours fill quickly during peak season (December-March). We recommend booking at least 2-4 weeks in advance for best availability. Last-minute bookings are possible but tour selection may be limited.
Can children go on northern lights tours?
Yes, but consider the late hours (most tours return after midnight) and cold temperatures. The Aurora Viewing Lodge tour is most family-friendly due to indoor facilities and shorter duration. We do not allow children under 10 on the Arctic Circle tour due to 14-hour length.
