Nha Trang is very beautiful! the beach, the sea and blue sky! people are friendly. Very relaxing place to visit after we arrived from Ho Chi Minh City.
There's also an amusement park for families, but we preferred to drink Coconut on the white beach :)
We also found out a new "smart" tourist information hotline that the city has just launched and it was pretty useful for us, simple dialing from your phone *2258 and it even supports Chinese!
