where to go in this Christmas
 

I have a plan come to Vietnam in this Christmas. But I don't know where is beautiful such as Halong, Sapa,....give me some advance

hoi an
hanoi

Hoi an, hue sapa, Hanoi and Halong bay - all wonderful. If you click on my name, you will find my trip report. I'm also happy to share my notes with you if you email me.

Sapa and Halong Bay can be very misty and cold - you can even get snow in Sapa at that time of the year. You might want to look at a weather site for each place you are considering www.weatherbase.com

thank dear friend. I also find out more some information. But I love Halong. I see it's beautiful. So to come to halong,should I book from my country or contact Vietnam agency to book?

Wait until you are in VN to book through a local agency. It will cost you much. much more to have an agency in your country book for you.
