7 Best Glaciers Near Anchorage, Alaska (And Exactly How to Visit Each One)
When I lived in Alaska, I made it my mission to visit as many glaciers as possible! I've walked on glacier ice, landed on one by helicopter multiple times, hiked to overlooks, and eaten a picnic lunch on a beach directly in front of a glacier wall. Here's everything I would tell a friend before visiting glaciers in the Anchorage area!

Hey Siri, play "Alaska" by Maggie Rogers. 🎶
Alaska has over 100,000 glaciers. Crazy, right? Narrowing down which ones to visit - especially if you're based in Anchorage and working with limited time - can be overwhelming. This guide cuts through that. Every glacier on this list is within a reasonable day trip of Anchorage, and I've been honest about which experiences are worth the effort and which ones are better suited to specific types of travelers.
The short version: if you can only do one, Matanuska gives you the most accessible walk-on-ice experience. If you want the most dramatic scenery, Portage Glacier via the Portage Pass hike is my personal favorite trail in all of southcentral Alaska. If budget is no object and you want something truly unforgettable, a helicopter tour to Knik Glacier is in a category all its own

Map of Glaciers Near Anchorage
In this map, each glacier (plus the glaciers’ access points) are sorted individually by color. For example: everything pertaining to Matanuska Glacier is labeled in green, and everything for Knik Glacier is in blue. All of the labeled spots are outlined in further detail within the blog post.
Glaciers North of Anchorage
1. Knik Glacier
Drive time: ~1 hour north of Anchorage Best way to visit: Helicopter tour or ATV tour
Knik Glacier is one of the largest glaciers in southcentral Alaska - over 25 miles long, with towering ice walls, deep crevasses, and in summer, pools of the most vivid blue water you'll ever see. It sits in the Chugach Mountains above the Knik River Valley, and without a guided tour you can really only see it from a distance via the short West Butte Trail in Palmer.
The way to actually experience Knik is by helicopter - and I say this as someone who has flown out there multiple times as an Alaska elopement photographer. It is breathtaking every single time. The approach alone - skimming over the Knik River and watching the glacier fill the entire windshield - is something I don't think I'll ever get used to. And landing on it, walking among those blue pools in midsummer when the ice is glowing from within? That's the kind of thing people mean when they talk about Alaska being unlike anywhere else on earth.
If the helicopter is outside your budget, the ATV tour through the Knik River Valley is a solid and super adventurous alternative that gets you to the glacier's edge without leaving the ground.
Getting there: Drive ~1 hour north of Anchorage to the Palmer / Knik River Valley area. Alaska Glacier Lodge is one of the main helicopter tour bases. For the ATV option, head to Alaska Backcountry Adventure Tours across the river.

2. Matanuska Glacier
Drive time: ~2 hours north of Anchorage Best way to visit: On-site guided tour (required to walk on ice)
Matanuska was the first glacier I ever walked on, and I still think about the feeling of standing on ancient ice for the first time. The sheer scale of it - the way it just keeps going in every direction, all cracked blue and white and grey - genuinely stopped me in my tracks. I couldn't stop staring.
What makes Matanuska special is accessibility. You drive right up to the tour building, lace up your boots, and within minutes you're on the glacier itself. No helicopter required, no serious hiking - just park and walk on ice. The guided excursion (required for safety, and very well-run) takes you through the terminus area for 2-3 hours, past crevasses, ice caves, and those extraordinary blue formations that form where the ice is oldest and most compressed.
For anyone wanting more, NOVA Guides offers a full-day backcountry ice climbing excursion on the glacier - a major step up in difficulty and reward.
If you want a bird's-eye view without the tour, the neighboring Lion's Head Trail is a short but steep hike with sweeping glacier views. Important note: it's on private land, so you'll need to "sign in" by phone - details are posted at the trailhead.
Getting there: Drive ~2 hours north on the Glenn Highway. Glacier access is through a privately owned area at milepost 102 - tour and access point here. A guided tour is required to walk on the ice; book in advance at glacier-tours.com.

3. Byron Glacier
Drive time: ~1 hour south of Anchorage Best way to visit: Self-guided hike
Byron Glacier is the easiest and most accessible glacier hike near Anchorage - a mostly flat, 2.4-mile round-trip trail that ends at a lovely viewpoint of a blue-hued glacier hanging in the valley above. You can't walk on Byron itself, but you get close enough to feel the cool air rolling off the ice, and in certain seasons there are ice caves at the base that you can peek into (but do not enter - they're incredibly unstable).
This is a great option if you're traveling with non-hikers, limited on time, or want a low-key glacier experience to pair with a visit to the nearby mountain town of Girdwood. It's also a beautiful trail in its own right - the valley it passes through is lush and dramatic, with glacier-fed streams crossing the path.
Getting there: Drive ~1 hour south on the Seward Highway. The trailhead is just past the Begich Boggs Visitor Center near Portage Lake. Parking is free and departs directly from the lot.

4. Portage Glacier - My Personal Favorite
Drive time: ~1.5 hours south of Anchorage Best way to visit: Portage Pass Trail hike
This is my personal favorite glacier experience near Anchorage, and it's not even a close call!
The Portage Pass Trail climbs to a high point with 360-degree views that I genuinely struggle to describe - ocean, mountains, and glacier all visible at once from a single spot. It's the kind of panorama that makes you stop talking mid-sentence. Then the trail descends to the shore of Portage Lake, and you find yourself standing on a beach directly in front of the glacier wall, watching ice calve into the water. The idea that you can spread out a picnic blanket and eat lunch right there, with a glacier as your backdrop, still feels slightly unreal to me even having done it.
Portage Glacier has receded significantly over the decades - it used to fill the entire valley - but what remains is still extraordinary. The combination of the pass views and the lakeside access makes this the most wonderful glacier experience in the area.
Getting there: Drive ~1.5 hours south on the Seward Highway, then turn onto Portage Glacier Road. You'll need to pass through the Whittier Tunnel - a one-way toll tunnel that alternates direction every 30 minutes, so check the schedule before you go. The Portage Pass trailhead is in Whittier on the other side.

5. Exit Glacier & the Harding Icefield
Drive time: ~2.5 hours south of Anchorage (near Seward) Best way to visit: Exit Glacier overlook trail, or the full Harding Icefield Trail for serious hikers
Exit Glacier sits at the edge of Kenai Fjords National Park, just outside the coastal town of Seward, and it's one of the most visited glaciers in Alaska for good reason - the trail network is well-maintained, free to access, and takes you through some of the most dramatic landscapes in the state.
I've done the Exit Glacier overlook trail multiple times and it never gets old. It's short enough for most fitness levels and gets you pretty close to the glacier face. Markers along the trail show the retreat line of the glacier over the decades - standing at the current glacier edge and looking back at where it was 50 years ago is sobering, to say the least.
The Harding Icefield Trail is a different beast entirely - ~8.5 miles round-trip with significant elevation gain, ending at a sweeping view of one of the largest icefields in North America. I haven't done the full trail yet and I'm saving it intentionally, because I want to give it the full day it deserves. It's firmly on my Alaska bucket list!
Getting there: Drive ~2.5 hours south to Seward, then follow Herman Leirer Road (Exit Glacier Road) to the end, where the Kenai Fjords Nature Centerand trailheads are located. No car? There's a seasonal shuttle from Seward.

6. Spencer Glacier
How to get there: Alaska Railroad's Glacier Discovery Train only (late May - mid September) Best way to visit: Train whistle stop + hike or rafting tour
Spencer Glacier is the most logistically unique entry on this list - you can only reach it by train, which makes the whole experience feel very adventurous. The Alaska Railroad's Glacier Discovery Train makes a backcountry whistle stop at Spencer, dropping passengers off for a few hours before returning to pick them up.
From the Spencer Whistle Stop station, you have about 3 hours to explore. Options include hiking the 1.3-mile trail to the glacier overlook above Spencer Lake (trail map), joining a guided rafting trip among the icebergs on the lake, or even staying overnight at a campsite or bench cabin before catching the next day's return train.
Book train tickets well in advance - this is a popular summer experience and seats go fast. Check the full Glacier Discovery Train schedule before planning your dates.
7. Raven Glacier via Crow Pass Trail
Drive time: ~45 minutes south of Anchorage (to Girdwood) Best way to visit: Self-guided hike
Raven Glacier is arguably the most demanding glacier on this list to reach - a ~7.5-mile round-trip hike via the Crow Pass Trail with over 2,400 feet of elevation gain starting from Girdwood. But for hikers who want to earn their glacier view in the most adventurous way possible, this trail delivers.
The route climbs through classic Chugach wilderness - forest giving way to alpine tundra, then rocky ridge - before the glacier comes into view from the overlook. For anyone wanting to extend it into an overnight, there's a public-use A-frame cabin along the trail - book it far in advance, as it fills up quickly in summer.
Getting there: Drive ~45 minutes south to Girdwood, then follow the dirt access road to the Crow Pass trailhead. Parking is free.
Honorable Mention: Glaciers in Prince William Sound
If you want to see a lot of glaciers in a single day (as in, more than 20!) a cruise or tour out of Whittier through Prince William Sound is the answer.
Prince William Sound Glacier Cruise: A full-day cruise through the fjords, past massive tidewater glaciers calving directly into the ocean. Lunch is included onboard and they offer a no-seasickness guarantee.
Prince William Sound Glacier Jetski Tour: If you'd rather experience the glaciers at speed and up close, Glacier Jetski Adventures out of Whittier outfits you in a drysuit and sends you out on your own SEADOO with a pro guide. One of the most unique glacier experiences available anywhere near Anchorage!

FAQ
Q: Which glacier near Anchorage is easiest to visit?
A: Byron Glacier is the easiest - flat trail, free parking, no tour required, about an hour from Anchorage. For walking on actual glacier ice with minimal effort, Matanuska is the most accessible option, though it requires a 2-hour drive and then a guided walk.
Q: Can you walk on a glacier near Anchorage?
A: Yes - Matanuska Glacier is the most accessible walk-on-ice experience and only requires a guided tour (no climbing gear, no special fitness level). Knik Glacier is another option, when you visit via helicopter. Byron, Portage, Exit, Spencer, and Raven glaciers are viewpoint-only on foot.
Q: What is the best time of year to visit glaciers near Anchorage?
A: Late May through early September is the ideal window. Days are long (sometimes 19+ hours of daylight in June), all tours and access roads are open, and the famous blue pools on glaciers like Knik are at their most vivid in July and August when surface melt is at its peak.
Q: How far is Matanuska Glacier from Anchorage?
A: About 100 miles, or roughly 2 hours north along the Glenn Highway. It's one of the most popular day trips from Anchorage and very doable without an overnight stay.
Q: Can you see a glacier from Anchorage itself?
A: Not directly from the city, but you can be standing in front of one within 45 minutes to an hour of leaving downtown. That's one of the things that makes Anchorage such an awesome base for traveling in Alaska!
Q: When are the blue pools on glaciers most visible?
A: The bright “Gatorade-blue” meltwater pools are most prominent from late June through early September. They form as warmer temperatures melt the surface ice, and are most dramatic during peak summer sunshine. If seeing the blue pools is a priority, aim for July or August.
Q: What should I wear to visit a glacier?
A: Layers are essential - it can be very cold near glacier ice even on a warm summer day, but it can also be surprisingly warm in full sun. Waterproof boots or sturdy hiking shoes, a warm mid-layer, a windproof outer layer, sunglasses (the glare off ice is intense), and sunscreen. For guided walk-on-ice tours like Matanuska, the tour operator will advise on any additional gear.
Final Thoughts
Alaska's glaciers are one of those things that photographs can't fully prepare you for. The scale, the color, the cold air coming off the ice, the sound of meltwater - it's a full blown sensory experience that honestly will stay with you forever.
If you're planning an Alaska trip based in Anchorage, I'd build at least two glacier days into your itinerary - i.e. one for Matanuska (for the walk-on-ice experience) and one for Portage Glacier via Portage Pass (for the hike and views). It’s up to you which ones you choose, but hopefully this complete guide has helped narrow down the options! Happy exploring - and welcome to the Last Frontier.
