Portage Glacier Cruises

Designed specifically for the glacial waters of Portage Lake, the M/V Ptarmigan features a fully enclosed, heated cabin, expansive panoramic windows, and an open-air upper viewing deck, providing exceptional comfort and unforgettable views in any weather.

Cruise across iceberg-dotted waters toward the towering face of Portage Glacier as your captain shares the fascinating natural and cultural history of Portage Valley and the surrounding Chugach National Forest. Keep watch along the steep mountain slopes, where mountain goats are often seen navigating rocky cliffs high above the lake, while bald eagles and other wildlife add to the experience.

Operating under a special use permit, the M/V Ptarmigan is built to U.S. Coast Guard specifications and designed with a low-draft hull to minimize environmental impact, ensuring a safe, quiet, and respectful journey through one of Alaska’s most spectacular glacial landscapes.
