Phong Nha has become a recent tourist destination. It's been recognized by UNESCO, and is home to some of the world's largest caves. As dark enclosed places aren't really my thing, it was a 24 hour stopover between Hue and Ninh Binh to break up the 15 hour bus ride. Being one of the poorest areas of the country, there wasn't much around, and life was very basic. It was a small stretch of buildings and small businesses nestled in the mountains.
