Located about 30 minutes north of Ninh Binh, the Vân Long Nature Reserve protects one of Northern Vietnam's largest unspoiled natural areas. Visitors can take a boat tour to see a small section of the park, and possibly spot the elusive, endangered Delacour's Langurs which call it home.
Phong Nha Cave isn't the biggest cave, or even the second-biggest, in the Phong Nha National Park. But it's the one which bears the park's name. So we felt safe assuming that it would be spectacular. And we weren't disappointed; this is an underground wonderland of stunning beauty.
