Born out of continuous tectonic orgies spread over millions of years, Ha Long Bay is one offspring mother Earth should be proud of! This limestone karsts jigsaw is Vietnam's prized heavyweight boxer that knocks everything else out and has single-handedly catapulted the country into travel bucket lists around the world. It's famous and it's crowded. Rightly so. The best way of banging the bay is getting yourself on a junk boat and spending a couple of days exploring the many caves and kayaking in the waters followed by scrumptious meals and late night revelries. Oh, and don't forget the sunsets you'll witness.
