Stunning limestone mountains as a UNESCO site

#bucketlistreboot Halong Bay as known as a UNESCO World Heritage Site is famous because its stunning limestone mountains raising up from emerald waters that formed from thousand years ago. You also can have a chance to explore amazing caves as well as the culture of Ha Long. There are plenty of activities to do at Ha Long. One of it is to take a cruise through this amazing limestone mountains and explore its cave system. In Ha Long bay, there is even a beach with its calm waves, definitely suitable for kayaking as well. I highly recommend to take an overnight cruise so that you have more time to do all these activities.
