Best way to travel Ho Chi Minh/Nha Trang & return. Train?

Plane would be a lot better. 35 minutes to Cam Ranh then a 40 minute taxi ride into NT, all up about $60-$70. Train would be a lot cheaper of course AND, a lot slower. If you do go by train and it stops at a siding just north of Phan Rang to let the southbound Express pass, have a look out the window you'll probably see me, either outside my inlaws house with my dogs or walking around taking photos.

Yes, Billy. Take the plane. It is faster and save more time :)

it is all depends of your choice: plane is fast and save time for othee things..train is very slower but you might get to see the countryside of the country...buses is ok tooo...
