River cruise ships are smaller than ocean-going cruise ships, typically holding 90-240 passengers (though there are ships that take only 5 passengers, and others can carry 1,000 passengers).

During river cruises the countryside is usually in view, so they are especially relaxing—and interesting—to those who prefer land nearby. River cruises usually last from 7 to 15 days, although some can last 3 weeks or longer.

Some river ships resemble 5-star hotels, with sun decks, dining rooms, lounges, fitness facilities, swimming pools, casinos and other entertainment. Accommodation, meals on-board, entertainment and special events (holidays, festivals, contests, concerts, etc.) are usually included in the cruise price, while bar expenses, sauna, massage, laundry and cleaning, and phone calls are not.

Most cruises have a variety of onboard and onshore activities. The latter include guided tours to historic and cultural sites, visiting local attractions, museums and galleries, and other points of interest. Guides give a running commentary while sailing.
