Hoa Lu, 100 km South of Hanoi, was the capital city of Vietnam under the Dinh Dynasty between AD 968 and AD 980. Some of the sanctuaries and tombs have survived the countless years and can still be visited today. Apart from the historical aspects, the area is also one of astounding natural beauty with limestone peaks whose splendor is often said to surpass that of Ha Long Bay. It is true that this area is often referred to as the Ha Long Bay on land. The tour includes being rowed along the Boi River, which makes for a truly unforgettable experience, passing between towering limestone peaks.
