Quang Binh province is a wild region of the barely penetrable jungle in Vietnam’s skinny middle, close to the border with Laos. The area is riddled with hundreds of deep caves, including one of the largest in the world Hang Son Doong. It contains a cavern so tall that a skyscraper could fit inside it.
The small town of Phong Nha is the epicenter for the area’s caving adventures, its eponymous cave another UNESCO-listed wonder well worth exploring. Here, you can hire both the guides and the gear you’ll need to descend into the caves.
If going underground doesn’t appeal, the area is also famous for trekking. The surrounding jungle is peppered with stunning waterfalls and an active (and noisy) population of monkeys and flying foxes.
