River Cruise Review: Viking River Cruises

As the world's biggest river cruise line, Viking River Cruises lays claim to the largest fleet, most extensive network of rivers and a wealth of experience navigating the world's waterways. In a nod to the company's Norwegian heritage, Viking River Cruise ships feature sleek, fairly minimalist Scandinavian-style interiors as well as pioneering hybrid diesel-electric engines, which reduce environmental impact as well as noise and vibration.
