They complement each other; most visitors who do both call the Spencer train ride the more adventurous outing, while the portage glacier cruise tours offer a relaxing alternative. These two Alaska landmarks provide distinct ways to observe ice formations near Girdwood.

Portage Glacier retreated more than a mile between 1914 and 2026, vanishing from roadside view and rendering the 1986 visitor center an observatory of absence.
What remains is Portage Lake, a two-mile basin of glacial meltwater scattered with icebergs the size of trucks, fed by tributary glaciers that still calve into the fjord. The retreat exposed a landscape geologists call a proglacial zone — raw till, kettle ponds, and bedrock scraped clean during the Pleistocene. Visitors no longer see Portage Glacier from shore, but the portage glacier cruise tour brings passengers within a quarter-mile of the ice face, close enough to hear the crack and splash of calving events.
The MV Ptarmigan, a 200-passenger catamaran operated since 1997, crosses Portage Lake in one hour, narrating the glacier's recession and the dynamics of iceberg formation. Rangers point out hanging valleys, lateral moraines, and the blue compression layers visible in floating ice. The lake sits at 150 feet above sea level, surrounded by peaks exceeding 5,000 feet in the Chugach Range. Black bears forage the shoreline in late summer, and mountain goats traverse cliffs above the waterline. The cruise departs from a dock at Byron Glacier Road, accessible via the Seward Highway, and operates between late May and mid-September when the lake is ice-free.
Portage Glacier's retreat is among the most documented in Alaska, tracked by the US Geological Survey since 1906. The glacier advanced during the Little Ice Age, reaching its maximum extent around 1850, then began a steady withdrawal that accelerated after 1980. By 2020, the terminus had separated entirely from the lake, forming a land-terminating rather than tidewater glacier. The portage glacier cruise experience adapts to this shift, focusing on the icebergs and tributary glaciers rather than the main terminus. The landscape continues to change; sediment plumes color the water turquoise, and new vegetation colonizes the exposed valley floor. The cruise provides the only waterborne access to this glacial remnant, a 90-minute round trip from Girdwood that compresses millennia of geological process into a single crossing.

A step-by-step walkthrough of Portage Glacier Cruise tickets — what you'll see, how long each stage takes, and the details that matter.
You arrive at the dock on Byron Glacier Road, where the MV Ptarmigan waits at the concrete pier. The boarding process takes ten minutes; crew members check your ticket and direct you to the upper or lower deck.
The catamaran pulls away from shore at 10:30, and within five minutes you are surrounded by icebergs, some no larger than a car hood, others the size of small houses. The water is a milky blue-green, opaque with glacial flour.
The captain slows near the largest icebergs, and you move to the rail to photograph the compressed blue ice. A ranger explains that the blue color comes from ice layers where air bubbles have been squeezed out over centuries. Fifteen minutes into the cruise, the boat turns toward Burns Glacier, a hanging valley glacier visible on the eastern slope. You hear a distant rumble, then see a car-sized block of ice break away and crash into the lake. The splash sends ripples across the surface.
The return leg follows the western shore, where the captain points out a black bear foraging near the waterline. You spend the final ten minutes on deck as the boat approaches the dock, the Chugach peaks framing the valley behind you.
