Sapa town is considered the second most popular attractions in the North Vietnam after Halong bay, it's quiet nice with the mountainous area, rice terraces, the hill tribes there,... but it's about 400 kms far from Hanoi - the capital of Vietnam, the arrival point. The best way to get there for tourists from is by train. You should take an 8 hour night train to Lao Cai Train Station and then take a bus 38 kms further to Sapa. If you are in Danang, you can fly to Hanoi and then go to Sapa.

Enjoy your trip!
