Viking Europe, Viking Neptune, Viking Pride and Viking Spirit are four sister ships that set the bar for river cruising in Europe when they were launched in 2001. They feature a beautifully designed layout of public areas and a wraparound deck that allows guests to enjoy scenery in the open air any time they wish, even during canal lock transiting or while sailing under low bridges; each ship accommodates just 150 guests in spacious staterooms, most with windows that open.
