I realise this is a very broad question and that 10 days is very little in Vietnam (well, more 9 days since I fly home on the 10th day), but I wondered what kind of itinerary I could have for this time in Vietnam?
I aim to arrive in Hanoi on the 25th September from China. And need to be in HMC on the 5th October to fly home. What could I realistically see within this timeframe? I guess I would like to see all the prettier spots and maybe chill some time on the beach/dive maybe, since I'll have done heaps of travel in China beforehand. Halong bay is definitely on the list (although I believe there is a less touristy option close to Halong bay but equally beautiful?). I'd also like to see Mekong delta and some of the tunnels from the war.
Any help on an itinerary would be appreciated. If I get a general idea, I can maybe work on the specifics from there - trains/flights, etc. Train is my preference though.
