River cruise popularity has gained momentum in the past five years, to the point that many river cruises are more popular than ocean cruises. River cruise ships are in demand and have recently become more luxurious and adventurous, providing a cruise for anyone from wine lovers to those who want a singular holiday or shopping experience abroad. River cruises provide three things that ocean cruises do not: a smaller ship, a guaranteed view of the water, and visits to more countries with a more cultural focus on shore tours. For those looking for a less-crowded, more local, and less travel-intensive experience, river cruises are an excellent choice. The only difficult choice may be which cruise to go on; the options are extensive, and there are many different cruise lines to choose from. The following cruises have received rave reviews, and are considered the top three European cruises available.
