Take the Spencer Glacier Whistle Stop Train in Alaska

Updated November 2026, Visit Spencer Glacier on the Whistle Stop Train was originally written in June 2017

Spencer Glacier is one of the most accessible backcountry glaciers to visit from Anchorage, despite having no road access. Located in the Chugach National Forest, Spencer Glacier sits at the head of Spencer Lake, where enormous blue icebergs float beneath a towering wall of ice surrounded by the Kenai Mountains.

While several guided tours visit Spencer Glacier, you don’t necessarily need to spend hundreds of dollars on an organized excursion to experience it. The Alaska Railroad’s Glacier Discovery Train stops at the remote Spencer Glacier Whistle Stop, where you can hike to the glacier independently, kayak among icebergs, or even camp overnight.

I’ve visited Spencer Glacier and put together this guide to help you plan your own trip. Below, I’ll cover everything you need to know about the Spencer Glacier Whistle Stop train, ticket prices, schedules, hiking trails, kayaking, camping, and how to visit without booking an expensive guided tour.

Whether you’re planning a day trip from Anchorage or want to spend a night in the Alaskan backcountry, here’s how to visit Spencer Glacier independently.

Cost of visiting Spencer Glacier

Visiting Spencer Glacier independently isn’t completely free, but it can be considerably cheaper than booking an organized kayaking or rafting excursion.

Your biggest expense will be the Alaska Railroad ticket. The Glacier Discovery Train is the only scheduled passenger train serving Spencer Glacier Whistle Stop, and the remote location means you can’t simply drive there yourself. Along with that, it is very expensive when you consider the meager distance.

One way to reduce the cost is to board at Portage rather than Anchorage. Portage is considerably closer to Spencer Glacier, so you can avoid paying for the longer train journey from Anchorage.

If you’re traveling on a budget, this is one of the best ways to experience Spencer Glacier for a little less.

Book Spencer Glacier Train Tickets

The easiest way to reach Spencer Glacier independently is by booking a round-trip ticket on the Alaska Railroad’s Glacier Discovery Train.

You can purchase tickets directly through the Alaska Railroad website. Select Spencer Glacier Whistle Stop as your destination when booking.

If you’re trying to keep costs down, I recommend boarding at Portage Stop 2 rather than Anchorage as mentioned previously. The shorter journey makes the ticket considerably cheaper, and you’ll still get to experience the scenic ride through the Placer River Valley.

2027 Spencer Glacier train ticket prices

Route	Adult	Child
Portage to Spencer (return)	$96	$48
Anchorage to Spencer (return)	$158	$79

Children under two travel free when seated on an adult’s lap. The Alaska Railroad also offers a 20% discount on published fares for eligible active-duty and retired US military personnel and their eligible dependents.

Tickets are subject to availability, so I recommend booking ahead, particularly if you’re traveling during the busy summer months.

Spencer Glacier Whistle Stop Schedule

The seasonal Glacier Discovery Train operates between Anchorage, Girdwood, Whittier, Portage, Spencer Glacier, and Grandview.

The train generally operates daily during the summer season, from late May through mid-September. However, the full route and Spencer Glacier service dates can vary at the beginning and end of the season.

The journey from Portage to Spencer Glacier takes approximately 15 minutes, while the ride from Anchorage takes around four hours.

Always check the official Alaska Railroad schedule before traveling, as departure times and operating dates can change.

How to Get to Spencer Glacier from Anchorage

There are two main options for reaching Spencer Glacier Whistle Stop: take the Glacier Discovery Train from Anchorage or drive to Portage and board the train there.

From Anchorage

If you’re taking the train from Anchorage, head to the Alaska Railroad’s downtown depot at 411 W. 1st Avenue, near the Port of Anchorage.

The Glacier Discovery Train departs Anchorage in the morning and travels south along Turnagain Arm before continuing through the Placer River Valley toward Spencer Glacier.

From Portage

Taking the train from Portage is the cheaper option and is what I’d recommend if you’re driving yourself.

Portage is approximately 50 miles south of Anchorage along the Seward Highway. Follow the highway toward Whittier and look for the Portage rail depot (Portage Stop 2) near Milepost 80.

Pull into the parking lot on the left side of the road (the side opposite from the ocean if you’re at all confused). There is a building with a red roof in the parking lot with a sign that says ‘Kenai Fjords Tours’.

Once you’ve parked, head toward the station building and follow the signs for passengers boarding the Glacier Discovery Train. Check your ticket and boarding instructions carefully.

Bring your luggage up to signs designating where to bring bags. They will first load the passengers on pre-booked tours luggage into one car. They will then load you mere DIY peasants’ luggage onto the second car. Don’t worry, they’ll make announcements. Just hand your bag to the baggage handler and then get on the train.

You can pretty much bring whatever you want: camping gear, bicycles, kayaks, rafts, SUP, your dog… etc.

*You can bring pets! Just bring their kennel and load them up with the luggage. 

Riding the Glacier Discovery Train to Spencer Glacier

The train ride to Spencer Glacier is an experience in itself. The Glacier Discovery Train follows some of Southcentral Alaska’s most scenic railway, passing mountains, forests, rivers, and glaciers before heading into the remote Placer River Valley.

If you’re boarding at Portage, the ride to Spencer Glacier takes approximately 15 minutes.

Seats are assigned on your boarding pass, although you may be able to move around if the train isn’t full.

Personally, I think the left side of the train offers the best views on the journey toward Spencer Glacier, while the right side is preferable on the return. That said, the scenery is spectacular from both sides.

The train makes several stops along the way, including one where rafts are loaded for the Spencer Glacier float trips.

When you arrive at Spencer Glacier Whistle Stop, listen for the announcements directing passengers to disembark.

Tour passengers and their equipment are unloaded according to the railroad’s loading arrangements, so follow the crew’s instructions.

Once to the whistle stop, you’ll find a covered shelter, restrooms, and the trailhead for the walk toward Spencer Lake. And then, well, you’re pretty much on your own in the wilderness.

Hiking to Spencer Glacier

Spencer Glacier Lake Trail

Once you get off the train, look for the gravel path leading away from the whistle stop. There’s a sign marking the Spencer Glacier Trailhead.

The trail is relatively flat and easy to follow, making this a straightforward hike for most visitors.

Follow the gravel path toward Spencer Lake, where you’ll get your first views of Spencer Glacier and the enormous icebergs floating in the water.

The walk to the lake and glacier viewing area is approximately 1.3 miles each way. There are restrooms along the route, including facilities near the lake.

This is the main walk most day visitors will want to do, and you don’t need a guide to follow the maintained trail.

Hiking from Spencer Lake Toward Spencer Glacier

Once you’ve reached Spencer Lake, you can continue exploring the shoreline and surrounding area for closer views of the glacier.

The terrain beyond the maintained trail is considerably different from the easy gravel path. You’ll encounter uneven ground, glacial moraine, loose rocks, and potentially unstable terrain.

There are several good viewpoints along the way, but use caution as the conditions of the routes can change.

If you want to explore beyond the established viewing area, make sure you have appropriate footwear, navigation skills, and experience with glacial terrain.

Kayaking, Rafting, and SUP at Spencer Glacier

One of the coolest ways to experience Spencer Glacier is from the water.

If you bring your own kayak, packraft, raft, or stand-up paddleboard, you can explore Spencer Lake and get a different perspective of the glacier and its enormous floating icebergs.

You’ll need to carry your equipment from the whistle stop to the lake, so factor that into your plans.

When we visited, we found that the wind tended to settle down later in the evening, making paddling more pleasant. We personally preferred heading out after 9 PM when conditions were calmer.

However, don’t assume that the lake will always be calm in the evening. Wind and weather conditions can change quickly.

Safety when kayaking Spencer Lake

This is not a casual paddle around a little alpine lake.

Spencer Glacier actively calves into the lake, and falling ice can generate large, unpredictable waves. Icebergs can also roll without warning.

The Forest Service recommends maintaining at least 500 yards of distance from the glacier because of the risk of calving waves. Keep your distance from icebergs too as 90% of the berg sits beneath the surface and they do roll. 

Cold water, unpredictable weather, and remote access make this a serious undertaking. Wear an appropriate personal flotation device, carry suitable cold-water equipment, and never paddle beyond your abilities.

If you’re inexperienced with glacier kayaking, I strongly recommend booking an experienced guide instead.

Can You Walk on Spencer Glacier?

Yes, it is possible to explore Spencer Glacier on foot, but this is not something I’d recommend attempting without appropriate glacier travel experience or a qualified guide.

Glaciers are constantly moving. Crevasses, unstable ice formations, hidden meltwater channels, and collapsing ice can make seemingly harmless areas extremely dangerous.

If you’re planning to travel onto Spencer Glacier, you’ll need appropriate glacier equipment, including crampons and crampons and ice axes, as well as the knowledge to use them properly.

During our visits, we encountered beautiful blue meltwater pools and fascinating ice formations. There were also ice caves along the glacier’s front face.

However, the ice cave featured in my older photographs has since collapsed. Ice caves are particularly unstable, and you should never enter one simply because it appears accessible.

My recommendation: If you want to walk on Spencer Glacier, book a guided glacier excursion with an experienced professional rather than attempting it independently, unless you have glacier travel experience.

Camping at Spencer Glacier

If you have the time, I highly recommend spending a night at Spencer Glacier rather than making this a rushed day trip.

Camping gives you more time to explore the lake, enjoy the surrounding mountains, and experience the area after the day-trippers have boarded the train back to civilization.

There are options for both backcountry-style camping and developed group camping at Spencer Lake.

Free Dispersed Camping

You can camp in suitable undeveloped areas around Spencer Glacier, provided you follow Forest Service regulations and avoid damaging vegetation.

When we visited, we found several clearings where we could pitch a tent. I recommend choosing a sheltered location away from the exposed lakeshore, as the wind can pick up.

Remember that this is bear country. Keep food, toiletries, and anything with an odor in the bear boxes near the raft launching point at the lake (not far from the outhouse) or in a bear vault. Never keep food inside your tent.

Developed group campsites

There are two developed group campsites at Spencer Glacier Whistle Stop:

Campsite	Maximum capacity
Campsite A	15 people
Campsite B	10 people

Both sites share a common area with picnic tables, a fire ring, tarp poles, a bear box, and a vault toilet.

These developed group sites are reservation-only and are not available on a first-come, first-served basis. Book through Recreation.gov.

Spencer Bench Public Use Cabin

If camping isn’t your thing, you can also stay at the Spencer Bench Cabin.

This public-use cabin sits approximately 1,900 feet above sea level and offers impressive views over the Placer River Valley and Spencer Glacier. The hike from the Spencer Whistle Stop is 5.4 miles each way.

Getting there requires a considerably more strenuous hike than the walk to Spencer Lake. The route involves climbing approximately 1,800 feet over three miles, with steep sections along the way.

The cabin is a great option for those wanting to spend a night in the backcountry without carrying a tent and all their camping equipment.

Reservations are required. You can book the Spencer Bench Cabin through Recreation.gov, and I recommend checking the current access information and reservation availability before planning your trip.

Guided Spencer Glacier Tours

Although you can visit Spencer Glacier independently, there are several guided excursions available if you’d prefer to have someone else organize the logistics.

Here are a few options worth considering.

Overnight Glamping at Spencer Glacier

If you want to experience Spencer Glacier overnight without bringing all your own equipment, Ascending Path has offered fully outfitted overnight camping adventures.

These trips include camping equipment, meals, guides, train transportation, and a helicopter transfer from the glacier area to Alyeska Resort in Girdwood.

The experience is considerably more expensive than visiting independently, but it offers a very different way to experience Spencer Glacier.

Guided Hikes at Spencer Glacier

The Chugach National Forest Service has offered ranger-led walks at Spencer Glacier during the summer.

These are a good option if you’d like to learn more about the surrounding landscape, glacial history, and local environment while exploring the area.

The Alaska Railroad also offers a Whistle Stop experience with an optional interpretive talk from a Forest Service ranger at the glacier overlook.

Spencer Glacier Kayaking and Rafting Tours

If you’d rather explore Spencer Lake with an experienced guide, there are organized kayaking and rafting excursions available.

One option is the Spencer Glacier float with Chugach Adventures. This excursion takes you by train to Spencer Glacier Whistle Stop, where experienced guides row among the icebergs before continuing down the Placer River.

It’s a great way to see the glacier from the water without needing to bring your own equipment or have extensive paddling experience.

Helicopter Tours to Spencer Glacier

Another way to experience Spencer Glacier is from the air.

Helicopter tours in the Girdwood and surrounding area offer a completely different perspective of the glaciers, mountains, and ice-filled valleys of Southcentral Alaska.

Depending on the operator and itinerary, you may be able to arrange a glacier landing or aerial sightseeing experience.

If you’re considering a helicopter excursion, compare departure locations, flight times, landing opportunities, and whether glacier activities are included.

Important Tips for Visiting Spencer Glacier

Before boarding the Glacier Discovery Train, there are a few things to know about visiting Spencer Glacier.

• Don’t miss the return train: The train departs Spencer Glacier Whistle Stop at approximately 4:40 pm. Be back at the whistle stop well before departure so you have enough time to collect your belongings and board.
• Bring everything you need: There are no shops, restaurants, or regular services at Spencer Glacier Whistle Stop.
• Pack food and water: Bring enough food and drinking water for your visit, particularly if you’re planning to hike or camp.
• Be bear aware: Black and brown bears inhabit the area. Carry bear spray, know how to use it, and store food properly.
• Dress for changing weather: Even during summer, temperatures can be cold near the glacier. Bring waterproof layers and warm clothing.
• Check train operating dates: The Glacier Discovery Train is seasonal, and Spencer Glacier is not accessible by scheduled passenger train throughout the year.
• Plan for limited connectivity: Don’t rely on having mobile phone service in this remote part of the Chugach National Forest.
• Respect the glacier: Maintain a safe distance from the glacier face and floating icebergs. Calving and iceberg movement can happen without warning.

One particularly important detail: if you’re planning to camp overnight, make sure you book the appropriate return journey. Don’t assume the standard day-trip ticket will accommodate a later departure.

Is Spencer Glacier Worth Visiting?

Spencer Glacier is one of my favorite ways to experience Alaska’s backcountry without having to to stray far from Anchorage. The scenic train ride, easy hike to Spencer Lake, towering glacier, and enormous floating icebergs make this a pretty special place to visit.

Whether you make Spencer Glacier a day trip from Anchorage or pack your camping gear and stay overnight, it’s well worth adding to your Alaska itinerary. Just remember to plan ahead, book your train tickets, and come prepared for unpredictable wilderness conditions.

If you’re looking for a more independent way to experience Alaska’s glaciers, the Spencer Glacier Whistle Stop is hard to beat.
