A daily "express" ferry service leaving at 7 a.m. runs down the Ayeyarwady (Irrawaddy) from Mandalay to Bagan taking 8-9 hours (or something like 20 miles per hour). One-way ticket is US$40 + US$5 commission (as of October 2014). It is more of a slow pleasure cruise than a rush express trip for the priceless river views and fresh air, a glimpse into the Myanmar country life with locals waving at you and acknowledging your presence non intrusively, and the overall soothing and relaxing atmosphere detached from misery and distant from poverty. Price includes a boxed breakfast, coffee, and lunchtime stir fry. Arrival times vary from 3 p.m. - 5 p.m. Water (500 kyat) and beer (3,000 kyat) is available onboard. The ferry can be booked by most hotel front desks. (Disagree: the views are far from spectacular from the middle of the very wide river. Frankly an overnight bus ride might cater to many more people at a fraction of the cost.)
A (very) slow ferry covers the same route frequently and costs US$10. Takes anything from 14 to 17 hours, but is a great opportunity to mix with the locals. Plastic chairs are available to rent on board. Otherwise, bring something to sit on and a cover for the early hours (leaves around 5am) and evening. Locals will be very happy to share theirs if you ask or if they see you shivering. Be aware, especially during dry season, that it's relatively common to get stuck on sandbars. If this happens, the trip may take two days. However, it's a great experience; the quintessential Burmese travel style.
The ferry services from Mandalay to Bagan will be shut down, except for the slow ferry ( available only on certain days in the week), during the months of April, May and June when the water level in the river is low. Please check with local travel agents while planning the trip.




如有用，请点

基本上每天有，去码头以及在酒店都能够问到。但是是不是被订完了就要另外说了。我的建议是，如果特别特别想坐的话，你可以提前在Booking上预定住宿一家酒店，然后打电话问他们你同时想坐第二天的船，能否让他们帮忙看看以及预定，这样就能做到提前预定了。或者可以在其他城市找旅行社让他们代订，这就要花点时间在找旅行社上了。
另:作为坐过这趟船的游客，觉得也就这样，主要还是浪费了宝贵的一个白天的时间。想体验东南亚江上景色的话，可以茵莱湖包小船或者蒲甘日落时分包船看日落，你能获得的是与河面更近距离的接触以及一个人发呆的空间

现场去看也行，没船改汽车，汽车班次很多的。

主要还是想体验下坐船，谢谢回复
