The Best Ways to See Alaska’s Glaciers: A Guide to 7 Iconic Ice Adventures

Alaska is home to roughly 100,000 glaciers – more than any other state in the U.S. They cover nearly 5% of the Last Frontier in year-round ice. From massive tidewater glaciers that calve house-sized chunks into the sea to ancient rivers of blue ice flowing out of remote mountain icefields, these are some of the most awe-inspiring landscapes on Earth. They’re also disappearing. Many of Alaska’s most iconic glaciers have retreated dramatically over the past century, and trail markers along places like Exit Glacier show – sometimes in just a few feet of ground – how quickly the ice is changing. Seeing them now isn’t just a bucket-list trip; it’s a chance to witness landscapes that may look very different in a generation.

The best Alaska glacier tours aren’t viewed from the deck of a cruise ship. They’re experienced by kayak, canoe, raft, or on foot – getting you close enough to hear the ice crack, feel the cold air pouring off the face, and stand on the glacier itself. In this guide, we’ve rounded up 7 of Alaska’s most iconic glaciers and the best human-powered ways to explore each. From family-friendly day trips that work for kids as young as 5, to strenuous full-day glacier hikes, to multi-day expeditions camping on remote beaches in front of calving ice, there’s an adventure here for every skill level. Every trip is run by vetted local outfitters and guides, and every booking helps fund conservation through TripOutside’s partnerships with The Conservation Alliance and Leave No Trace – because these glaciers aren’t just scenery. They’re home to harbor seals, sea otters, humpback whales, orcas, puffins, bald eagles, black bears, and Steller sea lions, and protecting these wild places means protecting the wildlife that depends on them.

When to Visit Alaska’s Glaciers

Most Alaska glacier tours run from mid-May through mid-September, with peak season falling between June and August when daylight stretches to nearly 20 hours, wildlife is most active, and weather is at its mildest. June and July offer the warmest temperatures and the best chance for clear-sky paddling and hiking conditions, while late August and early September bring fewer crowds, lower prices, and the first hints of fall color in the surrounding mountains. A few experiences – like ice cave exploration at Kennicott – extend into shoulder season or even winter, but most kayaking and rafting trips are strictly summer-only. Book early: peak summer dates sell out months in advance, especially for multi-day expeditions and small-group trips. And no matter when you go, come prepared for Alaska’s famously moody coastal weather – rain, sun, wind, and ice in the same afternoon is just part of the experience.

Kayak Among Icebergs at Columbia Glacier

For paddlers wanting to trade the cruise-ship view for a kayak seat, our Columbia Glacier tours out of Valdez offer guided sea kayak adventures into Prince William Sound, home to one of the most active calving glaciers on the planet. Trips range from a single full day to eight days, depending on whether you want a day trip water-taxi-and-paddle outing among the bergs or a multi-glacier expedition with beach camps, rainforest hikes, and stops at sea lion colonies and remote rookeries.

Day trips deliver the iconic Columbia experience — paddling through an ever-shifting maze of floating ice with naturalist guides. Multi-day camping tours add time on Glacier Island and traverse through Heather Bay, visiting Shoup Glacier and Meares Glacier, paddling to shorelines filled with Steller sea lions, and setting up overnight camps on secluded beaches in front of the ice. Every option includes guides, gear, water-taxi logistics, and a front-row seat to a retreating tidewater glacier that no cruise deck can match.

Spencer Glacier: Paddle, Float, or Fly to the Ice

Spencer Glacier offers an entirely different Alaska glacier tour — tucked into the Chugach National Forest about an hour south of Anchorage, it’s one of the most accessible glaciers in the state, reachable by the Alaska Railroad’s whistle-stop service, by helicopter, or by raft. Our Spencer Glacier adventures out of Anchorage and Whittier showcase that range, with all single-day adventures designed for paddlers, hikers, and rafters who want to get on, around, or above the ice. Options run from a mellow scenic float on the Placer River to a combination kayak-and-raft “Magical Spencer Double,” wildlife-focused rafting through the Spencer-to-Placer canyon, and bucket-list helicopter drops that land you on remote alpine ridges for private hiking and paddling.

Whether you’re traveling with kids, looking for a beginner-friendly first paddle, or chasing a once-in-a-lifetime heli adventure, every option includes guides, gear, and shuttle logistics — leaving you free to take in calving icebergs, braided glacial rivers, and the kind of Chugach scenery you can’t see from the road.

Kennicott Glacier: Hike, Climb, and Paddle in Wrangell-St. Elias

Kennicott Glacier sits in the heart of Wrangell-St. Elias National Park – the largest national park in the United States – and feeds the Root Glacier just outside the historic mining ghost town of Kennecott. Getting there is half the adventure: the only road in dead-ends at the McCarthy footbridge, and from there you’re in one of the most remote and least-traveled corners of Alaska. These Kennicott area adventures are all based in McCarthy and run by vetted local guides, and offer just about every way to experience the ice and the alpine that surrounds it.

Options range from a 4-hour packraft on Kennicott Glacier Lake to half- and full-day guided hikes onto Root Glacier with crampons. For travelers chasing something more adventurous, the Private Ice Cave Exploration is a strenuous 5–6 hour journey along the edge of the 24-mile-long Kennicott Glacier, crawling beneath the surface through glowing blue passages where light seeps through cracks in the ice – challenging, condition-dependent, and unforgettable. Guided Ice Climbing on the Root Glacier is another standout, a 9-hour day where after a 2-mile hike to the ice, you’ll gear up with crampons, ice tools, and helmet and learn to climb vertical blue walls under views of 6,696-ft Donoho Peak and the mile-high Stairway Icefall – with the option to drop into a moulin, a vertical hole that plunges deep inside the glacier. There are options for an afternoon or a full day, whether you want to walk on a glacier for the first time or swing tools into vertical ice, every trip comes with gear, expert guides who know this landscape intimately, and the chance to experience a glacier valley most travelers will never see.

Mendenhall Glacier: Alaska’s Most Accessible Ice

Mendenhall Glacier is one of the most accessible glaciers in Alaska – just 12 miles from downtown Juneau, flowing 13 miles out of the massive Juneau Icefield and ending at the milky-blue waters of Mendenhall Lake. Our Mendenhall adventures out of Juneau focus on getting you up close to the ice in a way the visitor center viewpoint can’t match. Options include a 4-hour guided canoe tour across Mendenhall Lake, weaving between floating icebergs to a beach at the glacier’s face, and a 5.5-hour canoe-and-hike combo that adds a trek to the thundering Nugget Falls.

For travelers who want to actually walk on a glacier, the Mendenhall Glacier Guided Hike is a 6-mile day on the West Glacier Trail with views from the ice itself, while the standout Mendenhall Glacier Ice Adventure Tour combines a canoe paddle across the lake with a guided trek directly onto the glacier – crampons on, crevasses up close, and a chance to peer into deep blue meltwater pools. A nearby option also part of the same massive Juneau Icefield, the Norris Glacier Adventure, takes you by helicopter or boat to the more remote Norris Glacier for a hike on glacier ice paired with packrafting. Whether you have a half day between cruise port stops or want a full immersive day on the ice, every trip includes guides, gear, and shuttle logistics from Juneau.

Kenai Fjords National Park – Kayaking in Aialik Bay

Aialik Bay is the heart of Kenai Fjords National Park – a dramatic fjord fed by tidewater glaciers where calving ice, harbor seals hauled out on bergs, sea otters, puffins, and humpback whales are all part of a normal paddling day. Reaching Aialik requires a water taxi ride from Seward through Resurrection Bay and along the rugged Kenai coastline, which means fewer crowds and a more immersive wilderness experience than you’ll get at the road-accessible parts of the park.

Our Aialik adventures range from single-day trips to multi-day expeditions, all departing from Seward. The Ultimate Aialik Day Kayaking trip is a small-group, wildlife-focused day at the face of Aialik Glacier, where you’ll paddle among floating ice and watch house-sized chunks break loose and crash into the bay. The Captain’s Choice Kenai Fjords Kayaking Tour is a kid-friendly guide-led day where the route is chosen based on conditions, weather, and wildlife – often including Aialik or a nearby glacier-fed cove. And the Aialik Bay Ultimate Overnight Expedition (2–7 days) is for travelers who want to camp on remote beaches, paddle multiple glacier faces, and fall asleep to the boom of calving ice. Every trip includes guides, gear, and water-taxi logistics – leaving you free to focus on the ice and the wildlife.

Exit Glacier – Hike on Ice, Easily Accessible from Seward

Exit Glacier is the only glacier in Kenai Fjords National Park accessible by road, making it the easiest way to walk right up to (and onto) Alaska’s ice without a boat or helicopter. Flowing down from the massive Harding Icefield just outside Seward, Exit has retreated dramatically in recent decades – markers along the approach trail show where the terminus stood in past years, a sobering and tangible record of climate change.

This Exit Glacier hiking adventure out of Seward lets you experience the ice on its own terms. This 8-hour guided trek takes you onto the glacier with crampons to explore blue ice features, deep crevasses, and the surreal, ever-shifting landscape of an actively retreating glacier with expert guides who know every safe route across it. The tour is rated strenuous and rewards the effort with hours of real time on the ice — the kind of glacier experience most travelers only see from a viewing platform. Complimentary pickup from Seward accommodations is included, along with a central meeting spot for travelers without lodging in town – making this one of the most accessible ways to actually walk on Alaska’s ice, with no helicopter or boat required.

Northwestern Fjord: The Remote Edge of Kenai Fjords

Northwestern Fjord is the most remote and dramatic corner of Kenai Fjords National Park – a deep, glacier-carved fjord ringed by at least seven tidewater glaciers, including the massive Northwestern Glacier itself. Getting there from Seward is a longer journey by water taxi, which keeps visitor numbers low and the experience genuinely wild. Once you’re paddling, you’re in a landscape that feels more like Patagonia or Greenland than the lower 48 – sheer rock walls, dozens of waterfalls cascading directly into the sea, and a constant soundtrack of calving ice.

The Northwestern Fjord Day Trip is a full-day kayak adventure into the fjord, with the boat ride bookending hours of paddling among icebergs and glacier faces. For travelers chasing the full experience, the Northwestern Fjord Extended Overnight Kayak Trip (2–7 days) is a true expedition – camping on remote beaches, exploring multiple glaciers, and experiencing one of the most spectacular fjords in North America with no crowds and no cruise ships in sight.
