So I took my first swim. Not too bad. It was off the boat.
Now Halong Bay is a beautiful place and Vietnamese people will tell you how beautiful it is every chance they get..
BUT
It will not be beautiful for long if the Vietnamese do not learn to stop emptying their rubbish into it! There was household rubbish everywhere and it really put you off swimming in the water. Our boat has a rubbish bin out the back that was overflowing and rubbish was just blowing into the water. It's a disgrace. Most Vietnamese have not travelled to other countries so have no idea that this is bad. Just a few hundred miles away in the Gulf of Thailand there is a national park that has the same limestone islands as Halong Bay but the difference is that the water is crystal clear and people know not to use it as a rubbish tip!
Shame on you Vietnam.
We also saw some caves that are a major tourist attraction. They were lit up like a disco. I'm not even going to continue with this...
The pics though tell another story so dont go there! Just buy a postcard and say you went there!
