The most popular river cruise route in 2015 is a Dutch waterways voyage from Amsterdam, but Myanmar is the up and coming river cruise destination next year.

That's according to the well-known Cruise Holidays travel agency chain, which surveyed 1,300 of its agents to come up with the list.

The Holidays Cruise Trends report is an annual, in-depth look at actual cruise bookings made for the year ahead. The "Windmills and Tulips" itinerary through Holland on the Mosel, Rhine, Main and Danube rivers was also the most popular cruise in the year-end 2013 survey.

Second on the list is a cruise on the Rhine, Main and Danube rivers through central Europe, followed by a cruise in the Rhine River valley along the border of Germany.

When it comes to cruises outside of Europe, Myanmar made the list of five most popular cruises for the first time. The country, also known as Burma, has begun to relax its approach tourism after years of suspicion by its military rulers. Cruises from Mandalay and Pyay in Myanmar are tied as the fourth most popular non-European river cruises next year, following two river cruises in China and a cruise on the Mekong River in Vietnam on the agency's list.

"We believe the growth of the European river cruise traveler has created this demand from those looking to collect new destination experiences," said Kevin Weisner, senior vice president for sales at Cruise Holidays' parent company, Vacation.com.

Cruise Holidays also reported on bookings for ocean cruises, saying 50.5% of all bookings for next year were in the Caribbean region, followed by Europe at 12% and Alaska at 7.8%.
