At a Glance: A Travel + Leisure World’s Best 2016 winner, placing first in the Small Ocean Ship category. Small enough to navigate the stunning fjords of Patagonia but large enough for perks some other expedition vessels don’t have (there’s a gym onboard!), this expedition vessel wows passengers with knowledgeable local guides, great onboard lectures, and once-in-a-lifetime experiences.
