Sorry if this has been asked many times before.
We are two travellers arriving independently from China and so don't have the usual option of an organised tour from Hanoi. We have three days and would like to see Halong Bay (day boat tour?), Cat Ba Island, and possibly Bai Tho Mountain.
Is it possible to do Cat Ba island as a day trip from Bai Chay? And are there good options for day boat trips in Bai Chay?
Where would it be easiest for us to be based to get the most out of our three days? Is Bai Chay a more lively destination than Cat Ba? And is Cat Ba easier to get to than we think?
Thanks for any advice/information :)
