Hiking Under the Northern Lights in Alaska

The allure of the aurora borealis combined with Alaska’s rugged wilderness creates an unforgettable hiking experience. While the spectacle is breathtaking, successful and safe aurora hiking requires specific preparation and an understanding of Alaskan conditions. This guide provides practical advice for those planning to chase the lights on foot.

When and Where to Go

The aurora is most active from late August through April, with peak viewing typically occurring between 10 PM and 3 AM. Clear, dark skies away from city light pollution are essential. While Fairbanks is often cited as the prime aurora viewing city due to its interior location, Southcentral Alaska (including areas around Anchorage) offers excellent opportunities with proper planning.

• Southcentral Alaska Trails: For Anchorage-area hikers, consider trails that offer open views to the north and minimal light pollution.
• Flattop Mountain Trail (Glen Alps): While popular, its proximity to Anchorage means some light pollution. However, the elevation gain can offer clearer views above the city glow on strong aurora nights. Stick to the lower, wider sections in winter.
• Refuge Trails (Potter Marsh, Westchester Lagoon): Flat, accessible, but heavily impacted by city lights. Better for very strong aurora displays.
• Eklutna Lake Trails (Chugach State Park): A bit further out, offering darker skies. The Lakeside Trail is flat and wide, suitable for winter hiking, but watch for ice.
• Talkeetna/Willow Area: Driving north on the Parks Highway significantly reduces light pollution, opening up more viewing potential from roadside pull-offs or short, easy trails.
• Interior Alaska (Fairbanks, Denali): Offers the highest probability of strong aurora, but requires longer travel from Anchorage. Trails here are often more remote and demand greater self-sufficiency.

Essential Gear for Night Hiking in Winter

Temperatures can drop well below freezing, and conditions change rapidly. Layering is critical.

• Headlamp: Non-negotiable. Bring extra batteries. A red-light mode preserves night vision for aurora viewing.
• Warm Layers:
  • Base Layer: Moisture-wicking (merino wool or synthetic).
  • Mid-Layer: Fleece or down vest/jacket for insulation.
  • Outer Layer: Waterproof/windproof shell.
  • Insulated Parka: Essential for standing still while waiting for the aurora.
• Extremities: Warm hat (covering ears), insulated waterproof gloves or mittens (bring a spare pair), and wool socks.
• Footwear: Insulated, waterproof winter hiking boots.
• Traction: Microspikes or Yaktrax are crucial for icy trails. Snowshoes may be needed depending on snow depth.
• Navigation: GPS device or fully charged phone with downloaded offline maps (AllTrails, Gaia GPS). Compass and physical map as backup.
• Hot Beverages/Snacks: Thermos with hot tea or coffee; high-calorie snacks that won’t freeze.
• Emergency Kit: First-aid, fire starter, multi-tool, emergency blanket, whistle.
• Power Bank: For phone and other electronics, as cold drains batteries quickly.

Safety Considerations for Alaskan Night Hikes

Darkness, cold, and wildlife add significant risk. Never underestimate Alaskan winter conditions.

• Go with a Partner: Never hike alone at night in Alaska, especially in winter.
• Tell Someone Your Plans: Inform a trusted person of your exact route, expected return time, and vehicle description.
• Wildlife Awareness: Moose are active year-round and can be difficult to spot in the dark. Give them wide berth. While less common in winter, bears can occasionally be out. Carry bear spray, know how to use it, and keep it accessible (not buried in your pack).
• Stay on Marked Trails: It’s easy to get disoriented in the dark. Avoid venturing off-trail.
• Check Weather and Aurora Forecasts: Use resources like the Geophysical Institute’s aurora forecast (gi.alaska.edu/monitors/aurora-forecast) and local weather reports. Clear skies are paramount.
• Conserve Body Heat: Avoid sweating excessively. Delayer if you’re working hard, but re-layer quickly when you stop.
• Vehicle Preparedness: Ensure your vehicle is winterized and has emergency supplies (jumper cables, shovel, extra warm clothing, food/water).

What to Expect and Photography Tips

The aurora isn’t always a vibrant, dancing display. Be prepared for subtle greens and whites, or even no show at all.

• Patience is Key: Aurora viewing often involves long periods of waiting in the cold.
• Photography Gear:
  • DSLR/Mirrorless Camera: With manual controls.
  • Wide-Angle Lens: f/2.8 or faster.
  • Sturdy Tripod: Essential for long exposures.
  • Extra Batteries: Keep them warm in an inner pocket.
  • Remote Shutter Release: Reduces camera shake.
• Camera Settings (Starting Point):
  • ISO: 800-3200 (adjust based on light).
  • Aperture: Widest open (e.g., f/2.8).
  • Shutter Speed: 5-20 seconds (shorter for faster-moving aurora).
  • Focus: Manual focus to infinity.
• Enjoy the Moment: While capturing photos is rewarding, don’t forget to put the camera down and simply experience the magic of the aurora.

Hiking under the Northern Lights in Alaska is an extraordinary adventure. With thorough preparation, proper gear, and a strong emphasis on safety, you can create memories that will last a lifetime.
