Viking River Cruises' 198-passenger Viking Helvetia debuted in 2006. The ship plies the water of the Rhine River between Amsterdam and Basel, visiting ports like Cologne, Koblenz and Breisach, gateway to Germany's Black Forest.
Here's what you can expect onboard:

The ship has 99 outside cabins, with 37 featuring French balconies. The majority of cabins are 170 square feet; there are 10 smaller cabins that clock in at 151 square feet. Cabin amenities include TV, safe, hair dryer and bottled water (replenished daily). Electricity on the ships is 220V, but each cabin will have one or two 115V razor plugs available, generally in the bathroom.

Viking Helvetia has four decks, including a sun deck with shaded area. Interior spaces include a lobby atrium, an observation lounge with bar, an open-seating dining room, a boutique and a library. There are a few computers for passenger use.

Fares include shore tours and free Wi-Fi.
