Alaska has a place where glaciers collapse into the sea and you can watch it happen

Alaska’s ice is alive and it’s loud

Glacier Bay sits in the southeast corner of Alaska, a 3.3-million-acre tangle of mountains, ice, rainforest, and deep ocean fjords. More than 100 glaciers pour through its valleys and spill into the sea.

Towering peaks rise straight from the water with nothing but cold air between them and the sky.

This place is a UNESCO World Heritage Site, and once you’re out on the bay watching a wall of ice collapse into the ocean, you’ll understand why people come back.

The Huna Tlingit called this home long before the ice came

Long before any park boundary existed, the Huna Tlingit people lived on this bay, fishing, hunting, and gathering from its waters and forests for generations.

In the 1700s, a surging glacier swallowed their villages and pushed them out. When the ice finally pulled back, they returned.

That connection to Glacier Bay didn’t end there.

It continues today, woven into everything from the clan house on the shore to the stories told by Tlingit guides and rangers working inside the park.

Margerie Glacier rises 200 feet straight out of the sea

Margerie is the glacier most visitors come to see, and it earns the attention.

The ice runs about 21 miles back into the mountains, and where it meets the water, the face rises roughly 200 feet above the surface.

The color shifts between white and a deep, cold blue depending on the light and the density of the ice.

Margerie is one of the more active glaciers in the park, which means you have a real chance of watching it move while you’re standing there.

A calving glacier sounds like a building falling into the ocean

When ice breaks off a glacier and hits the water, the sound travels across the fjord before the splash even settles.

Big pieces, some the size of office buildings, drop with a boom that rattles the air and sends swells rolling toward any boats nearby.

Calving can happen without warning and last just a few seconds, or it can unzip across the glacier face in a long, grinding roar. For most visitors, this is the moment that stays with them long after they get home.

Humpback whales return to feed in these cold waters every summer

The bay pulls humpback whales back each summer because the water is cold and full of food.

On a good day, you see them breach, throwing their bodies out of the water before crashing back down, or slap the surface with their tails.

Some feed in groups, using bubbles to herd fish into a tight ball before lunging up through the middle.

Glacier Bay ranks as one of the best places in Alaska to watch humpbacks at work, and the viewing season runs through summer.

Orcas, otters, and seals share these icy fjords

Pods of orcas move through the fjords on their own schedule, hunting as they go.

Sea otters float on their backs in loose groups called rafts, drifting with the current and looking completely unbothered.

Harbor seals haul out on chunks of floating ice and sun themselves while the bay moves around them. Along the rocky shores, sea lions stretch out above the waterline.

The marine life here runs deep, and almost any time you’re out on the water, something worth watching turns up.

Brown bears and bald eagles patrol the shoreline

On shore, the wildlife shifts but doesn’t slow down.

Brown bears work the beaches and forest edges, flipping rocks and digging for whatever the tide left behind. Black bears roam deeper in the wooded areas of the park.

Moose move through the meadows and wetlands where the land flattens out near fresh water.

Above it all, bald eagles claim the tall dead snags along the water, and if you look up at the cliffs, mountain goats pick their way across rock faces that look completely vertical from the bay.

The West Arm boat tour puts the best glaciers right in front of you

The West Arm of the bay holds some of the grandest ice in the park, and the only practical way to reach it is by boat.

Day tours run deep into the bay and swing past Margerie and Grand Pacific glaciers as part of the regular route. Passengers watch for whales and wildlife the whole way out and back.

The views come at you from every direction, mountains on all sides and ice at the end of the channel, with no roads, no buildings, and nothing else in sight.

Johns Hopkins Glacier shelters seals and drifting blue icebergs

Johns Hopkins sits in its own inlet off the West Arm, and it draws a crowd even by Glacier Bay standards.

The ice carries a deep blue tone that stands out against the gray water, and icebergs calved from the face drift through the inlet in slow circles.

Harbor seals choose this spot to rest and raise their pups, which is why park managers restrict access to the inlet during early summer. If you go later in the season, you can get closer and the seals are still there.

Sea kayakers spend days paddling among glaciers and quiet coves

Sea kayaking is how you get inside the park on your own terms. Paddlers glide past glacier faces, remote beaches, and small coves that boat tours don’t stop at.

The daily tour boat can drop kayakers off farther up the bay, which opens up multi-day trips into the backcountry without having to paddle the full distance from Bartlett Cove.

Out on the water at that scale, you can drift close enough to floating ice to touch it, and otters, seals, and seabirds move around you like you belong there.

Bartlett Cove trails wind through mossy old-growth rainforest

Bartlett Cove is the only part of the park with any development, and it’s where most land-based exploring starts.

The Forest Loop Trail runs one mile through a rainforest of spruce and hemlock draped in moss, and part of the trail is gentle enough to walk without much effort.

The Bartlett River Trail leads out to a quiet estuary where the river meets the bay, a good stretch of ground for spotting birds and watching the light change over the water.

Neither trail is long, but both take you somewhere worth going.

The clan house on the shore tells the story of a people and their land

At Bartlett Cove, the Xunaa Shuká Hít clan house stands on the water’s edge, and it carries real weight.

It is the first permanent clan house built in the bay since the Little Ice Age, when the glacier pushed the Huna Tlingit from this ground.

Tlingit craftsmen carved the interior panels and totems by hand, and Raven and Eagle totems along with a Healing Pole stand close by.

You can walk through and hear the story of how this people lost their homeland to the ice and then came back for it.

Visit Glacier Bay National Park and Preserve in Alaska

You can reach Glacier Bay by flying or taking a ferry into the small town of Gustavus, then traveling about 10 miles by road to Bartlett Cove, the park’s main hub. There’s no entrance fee to the park.

The glaciers sit far up the bay, so you need a boat or kayak to see them up close. A park concessioner runs day tours up the West Arm from late spring through early fall.

The Visitor Information Station at Bartlett Cove has maps, permits, and ranger orientations to help you plan your time on the water.
