The beautiful Halong Bay, about an hour outside Vietnam's Ha Noi city is as awesome in reality as it is in pictures (albeit a little more crowded). There are literally thousands of boats running trips into the bay, some are amazing, others are grotty. Be sure that while booking a tour you are shown pictures of the boat you are supposed to be on, be sure to ask if that is the exact boat you will be getting on and tell the agent or hotel that you will be returning after your trip (even if you will not) and that you will book another tour with them if this one is good. Often times people on the same trip are charged totally different prices, sometimes $100's different. Be sure to do a little research about what the boat you want should cost and do not be afraid to bargain hard!
