Portage Glacier Cruises depart 1.5 mi. s. of the Begich-Boggs Visitor Center in the Portage Glacier Recreation Area. A 1-hour narrated cruise aboard the MV Ptarmigan takes passengers to the face of Portage Glacier. Sections of the glacier “calving” or breaking away into the lake below often can be seen. The 144-passenger ship has a climate-controlled cabin with oversize windows and an open-air observation deck. Shuttle and tour packages from Anchorage also are available.
