There is a saying that if you have not visited Ha Long Bay, you have not yet been to Viet Nam. On the other hand, we can say that if you have not visited Ha Long Bay, you have not yet seen the most beautiful place in the world. It takes us around 4 hours by bus to travel 180 km from Ha Noi towards the northeast to Ha Long Bay.
Ha Long Bay has been twice recognized by UNESCO as a World Heritage Site in 1994 and in 2000, and also that Ha Long Bay is in second place in the worldwide competition of the World's Seven Natural Wonders. 1,969 limestone islands of various shapes, sizes, and in different green and amazing colours rise above the sea level in an area of more than 1,500 square kilometres that creates this world heritage site. Ha Long Bay still keeps its historical and cultural values.
Ha Long Bay is attractive and beautiful throughout the four seasons: spring, summer, autumn, and winter. Travelling on small sailboats among hundreds of limestone islands, one may visit the amazing Surprise Cave, the floating fishing village, and see how the locals live, which are top of the list of things to do here. On Titov Island, one may swim and relax on the beach or enjoy a kayaking programme to the nearby Luon Cave and much more.
The experience of visiting Ha Long Bay is unforgettable, where you will see something that will stay in your mind and eyes for years. You will enjoy meeting Vietnamese people and tasting their delicious food. You will have fresh air all day and night, especially if you wake up early in the morning and watch the sunrise on the deck coming slowly through the islands. Be sure not to miss visiting Ha Long Bay in your lifetime.
