A tour of Vietnam is not complete without experiencing some of the country's trademark natural beauty. From the hiking haven of Sapa to the waters of the Mekong Delta, there are plenty of highlights to choose from, but you can't close out your visit without a trip to Ha Long Bay.
Located in the Gulf of Tonkin, Ha Long Bay has some of the most unique natural formations in the world thanks to the thousands of limestone inlets that spring out of the water. As a result, the unusual formations have become a popular tourist destination because of the many grottos and caves that populate the bay.
You can explore the bay via boat, but many travelers prefer to get a more up close look at the geo-diversity that's around every corner. If you're looking for a more hands-on experience, the Thien Cung Grotto is the place to go. Sometimes referred to as the Heavenly Cave, this enormous formation has become a popular day trip for many tourists.
Thien Cung Grotto is one of the most recently discovered caves in the bay, but that certainly does not make its interior any less impressive. In addition to the countless stalactites that hang from the high ceiling, visitors are often struck by the breathtaking artwork create by the hands of time.
