Phong Nha Kẻ Bàng national park, where to find the world’s biggest cave
Not long ago the sleepy village of Phong Nha barely got a mention in guidebooks, but the surprise discovery of one of the world’s largest caves has catapulted it into the adventure tourism spotlight. The Phong Nha-Ke Bang National Park is a rugged swathe of limestone mountains riddled with gigantic caves. It’s also home to endangered wildlife and ethnic minority groups. The gateway to this land of adventure is Phong Nha, a welcoming village on the banks of the graceful Son River.
