Discover the ultimate way to experience the Root Glacier – the Blue Pool Jump! Learn what a blue pool is, how to safely experience this glacier thrill with a guide, and what gear to bring for the ultimate Alaskan adventure.
What’s a “Blue Pool,” Anyway?
If you’ve been scrolling photos of glacier adventures in Alaska, you’ve probably seen it—a shimmering, electric-blue pool carved deep into the ice. These “blue pools” form when meltwater collects in pockets on the glacier surface, their vivid color created by the way dense ice absorbs and reflects light. They look almost unreal—like nature turned up the saturation dial just for fun.
And if you’re hiking on the Root Glacier, you might just have the chance to jump into one!
The Legendary Blue Pool Jump
The Blue Pool Jump is one of the most exhilarating (and refreshing!) moments you can have on a glacier. Imagine standing at the edge of a glowing pool, the ice around you sparkling in the sun, your heart pounding as you count down and leap into the coldest, clearest water you’ve ever felt.
But here’s the important part: this is not your average swimming hole. Glaciers are constantly changing, and blue pools vary in depth, temperature, and structure. A safe jump requires expert setup and knowledge of glacial terrain—that’s where your guide comes in.
Why You Should Only Jump with a Guide
Our professional guides know the glacier like the back of their hand. They’ll:
-
Scout a safe pool for depth, stability, and easy exit points.
-
Set up secure entry and exit systems using ropes or ice tools if needed.
-
Provide instruction on proper jump technique and cold-water safety.
Without that expertise, a blue pool jump can quickly become dangerous. With St. Elias Alpine Guides, it’s just pure, icy fun.
When Can You Do a Blue Pool Jump?
Because reaching the blue pools often requires hiking deep into the glacier, Blue Pool Jumps are only possible on our Full-Day Glacier Hike.
Half-Day Glacier Hikes are perfect for exploring crevasses, streams, and stunning glacier features closer to the trailhead—but usually don’t allow enough time to reach and assess safe jumping pools.
So if a polar plunge into an Alaskan glacier pool is on your bucket list, book the Full-Day Glacier Hike and let’s make it happen!
What to Bring for Your Blue Pool Jump
You’ll need all the standard gear from our Glacier Hike Gear List plus a few extra essentials for this chilly dip:
-
Socks – You’ll jump wearing socks for traction on the ice. Bring an extra dry pair to change into afterward.
-
Swimsuit or underwear – Depending on your comfort level, you can jump in a swimsuit, underwear, t-shirt, or even go for the bold buff! Just make sure you have something dry to change back into.
-
Towel – You’ll want to wrap up and warm up quickly!
-
Courage and a sense of adventure! – This is Alaska, after all.
Ready to Take the Plunge?
Whether it’s your first glacier hike or your hundredth, the Blue Pool Jump is an unforgettable way to connect with Alaska’s wildest landscapes. It’s cold, it’s crazy, and it’s completely unforgettable.
