During my trip to Vietnam I arrived by train and, frankly, Dong Hoi, wasn't very pretty at first sight. It was difficult to make ourselves understood by anyone but we got there and, a couple of steps from the station, a local rented us some motorbikes for a few days. I had the impression of a town I didn't like, stifling heat and exhausting bustle. The fishing port didn't have much charm until the end of the day when little bars opened up for the local Vietnamese.
We wanted to swim but the water was dirty and the environment polluted. The cafes selling seafood weren't very cheap but what can I say, it was delicious! There are a lot of hotels being built and the facilities aren't improving the area.
I really don't have good memories of Dong Hoi. When we arrived there on the night bus at 4 a.m., the taxi drivers demanded a fortune to take us the 1.5 km to the centre of town... The town isn't particularly pretty and has no real charm, even the seaside isn't very attractive.
You have to bargain for everything in Dong Hoi, even getting on the bus! Although there are fixed prices for going to Huê and other big towns, they refuse to take you unless you pay an extortionate extra amount! We rented scooters for a relatively normal price, but that were really badly maintained, to get to Phang Nha Ke Bang park, which is very beautiful but you have to pay for everything there as well...
The only upside is that you learn how to be patient and not to be taken for a ride!
The downside is the attitude of the locals.
