Heritage listed Ha Long Bay is a major tourist attraction in Vietnam, and rightly so.
The bay is home to over a thousand jungle clad limestone pillars, several of which are hollow and contain enormous caves.
I next visit Cat Ba Island, the largest island in the bay. Half of Cat ba is National Park.
I interview Tuan, a local cafe owner. He takes me for a tour of the island and we also visit a floating village, where people farm fish in small enclosures.
