The original plan was to stay on a junk boat over night in Halong Bay. Unfortunately a typhoon was supposed to hit and the government banned all boats from being out on the bay. We were really lucky the weather cooperated and we were able to go on the junk boat the next day for a four hour tour. There are about 3000 mini islands comprised of lime stone throughout the bay. Also there are many caves we stopped at two on the tour. They also served us a seafood lunch that was delicious.
