The top of Ba Vi National Park is Mount Tan Vien which is 1397m above the sea level.
On the top there's a nice cafe for you to get relaxed and to enjoy the chill. Here there are 2 temples for you to visit: One temple is dedicated to a general from the time that no one would remember; the other is to Ho Chi Minh. The hikes to the temples require a bit of physical efforts and the reward is well worth it. From Ho Chi Minh Temple you can get the panoramic view of the surroundings which look like an ancient painting: green mountains running along the Black River (Da River).
