For those that have been to both, would you recommend Hue or Phong Nha if you had to choose?
We are traveling from Hanoi to HCMC via the train. It will be in March.
Perhaps not a fair question, as they are very different places, but our time is limited and we either stop off in Hue for a couple nights, or in Phong Nha (disembarking the train at Dong Hoi), and I'm trying to decide between the two.
Comparisons aside, if anyone has visited Phong Nha I'd love to hear your thoughts about it.
