We'll take a boat trip to Ba Be Lake and explore the Puong cave. Then, the cruise continues to Cam Ha Village, where you can experience the peaceful life of the Tay people before getting back on the boat that takes you upstream along the Nang River. The river has slowly eroded the karst, eventually breaking through to the other side and leaving behind a great tunnel of fascinating rock formations. Finish the boat trip, get on the support vehicle at the park gate, and head out for lunch before transferring back to Hanoi. Ha Giang bike Tours
