Massive and magical, Hubbard is considered the mother-of-all tidewater glaciers in North America. Taller than a 30-storey building (above water). Larger than the state of Rhode Island. The marvel is also the most active, with ice chunks regularly sloughing off in massive dimensions. The thunderous roar of cracking ice echoes against a stellar backdrop with five of the ten tallest peaks in America. The most magical moment you’ll ever enjoy on deck.
