The experience
An hour's drive from Anchorage along the Seward Highway gets you to Portage, where you board the M/V Ptarmigan: a custom-built sightseeing vessel with a heated indoor cabin and an open-air top deck. The boat is designed to navigate glacial conditions, so you can get close enough to see the towering blue ice wall of Portage Glacier itself. During the one-hour cruise across Portage Lake, you pass floating icebergs and cascading waterfalls tumbling down the steep mountain cliffs on either side.
A U.S. Forest Service ranger provides live narration throughout the cruise, sharing details about the glacier's formation, the wildlife in the area, and the region's history. The ranger's commentary runs in English and is included with your ticket. If conditions align, you may witness calving (chunks of ice breaking away from the glacier face and falling into the lake), which produces both a visible and audible event. Bring binoculars or a camera to capture the details. The open-air deck and cabin windows both offer vantage points depending on weather and your preference.
The cruise operates daily from mid-May through mid-September, with five departure times each day so you can fit it into your schedule. The boat is wheelchair accessible, and infants can ride in a pram or stroller (infants must sit on an adult's lap during the cruise). Children under 12 need to be accompanied by an adult. Food and beverages are available for purchase onboard. Cancellations made at least 24 hours before your departure receive a full refund.

How far is Portage Glacier from Anchorage?
Portage Glacier is about an hour's scenic drive from Anchorage along the Seward Highway. The cruise itself departs from the glacier, so you'll need to arrange your own transportation from the city to the boat dock.
What happens during the one-hour cruise on Portage Lake?
The M/V Ptarmigan carries you across Portage Lake toward the face of Portage Glacier, passing floating icebergs and waterfalls along the way. A Forest Service ranger narrates the geology, wildlife and history of the area while you view the glacier's towering blue ice wall from either the heated cabin or the open-air deck.
Can you actually see ice calving off the glacier during the cruise?
Calving (the sight and sound of ice breaking away from the glacier face) can happen during the cruise, though it depends on conditions. When it does occur, it is one of the dramatic moments the cruise offers, and the ranger will point it out.
What's included in the ticket price?
The ticket includes admission to the cruise, use of the heated cabin and open-air deck, the one-hour journey on Portage Lake, and the ranger's narration in English. Food and beverages are available for purchase onboard but are not included.
How many times a day does the boat depart?
The M/V Ptarmigan runs five departures daily from mid-May through mid-September, so you can choose a time that fits your schedule.
Is the boat accessible for people with mobility needs?
Yes, the M/V Ptarmigan is wheelchair accessible, and all areas and surfaces onboard are accessible. If you need wheelchair space, notify in advance so the crew can reserve it for you.
