Alaska’s Glacier Bay National Park is already known for its breathtaking natural beauty, with its towering glaciers, pristine fjords, and abundant wildlife. However, Mother Nature occasionally adds an extra layer of enchantment to this already spectacular landscape. One such magical phenomenon is the Northern Lights, also known as the Aurora Borealis. These dazzling displays of lights in the night sky have been capturing the hearts and imaginations of visitors to Glacier Bay for centuries. In this blog post, we’ll explore the mesmerizing world of the Northern Lights as they put on a show above Alaska’s Glacier Bay National Park.

The Dance of the Aurora

The Northern Lights, scientifically known as the Aurora Borealis, are a natural light display that occurs predominantly in high-latitude regions near the Arctic and Antarctic. In the case of Glacier Bay National Park, it’s the Aurora Borealis that graces the northern Alaskan skies. These celestial wonders result from the collision of charged particles from the sun with Earth’s atmosphere. As these particles interact with gases in our atmosphere, they produce stunning colors and patterns that light up the night sky.

The Colors of the Aurora

One of the most captivating aspects of the Northern Lights is the array of colors they exhibit. While green is the most common color, you can also witness shades of pink, red, purple, blue, and even yellow during a particularly vibrant display. These colors are determined by the type of gas particles involved in the collision and their altitude in the atmosphere. Oxygen at higher altitudes, for example, can produce red and purple hues, while nitrogen can result in blue and green lights.

When to See the Northern Lights in Glacier Bay

The best time to witness the Northern Lights in Glacier Bay National Park is during the winter months, from late September to early April. This period provides the ideal conditions for clear, dark skies and a higher probability of catching a dazzling aurora display. It’s essential to check the local weather forecast and the aurora forecast for the park to maximize your chances of witnessing this natural spectacle.

Photographing the Aurora

For photography enthusiasts, capturing the Northern Lights is a dream come true. Glacier Bay’s remote and relatively untouched environment makes it an excellent location for astrophotography. To capture the perfect shot, consider using a tripod to keep your camera steady, a wide-angle lens to capture the expansive sky, and a remote shutter release to avoid camera shake. Experiment with different exposure settings to find the right balance between capturing the colors and preventing overexposure.

Experiencing the Northern Lights

While seeing the Northern Lights is undoubtedly a visual delight, it’s also a deeply emotional and spiritual experience for many. The eerie silence of the winter night, the crispness of the cold air, and the anticipation as the lights begin to dance above create a sense of wonder and awe that is unparalleled. It’s a moment that brings you closer to nature and reminds you of the beauty and majesty of our planet.


Glacier Bay National Park is not only a haven for natural beauty but also a front-row seat to one of the most mesmerizing displays nature has to offer—the Northern Lights. If you ever find yourself in Alaska during the winter months, make sure to venture into the heart of this pristine wilderness and gaze up at the night sky. With a little luck and a lot of patience, you might just witness the Northern Lights as they put on a breathtaking show above Glacier Bay. It’s a sight that will stay with you long after the lights have faded, leaving you with a profound appreciation for the wonders of the natural world.
