River cruising gives you the best of both worlds, plenty of time on the water combined with easy access to numerous ports along the way. Since cities often developed along the waterways, there are plenty of places to stop and explore while river cruising. River cruising is extremely popular in Europe, with the Danube being one of the longest and most popular rivers. The Mekong in Asia and the Nile in Africa are also great choices.
River cruising is also gaining steam in the United States with riverboat sailings along the Mississippi. There are some budget-priced options but many easily qualify as all-inclusive luxury experiences.
