Phong Nha - The Biggest Cave in the World

I joined a bicycle tour to the Phong Nha caves.  Besides being heavily touristed the caves are beautiful.  The only way to explore the cave is by a tourist boat which takes you some way into the cave.  It would be very pleasant if there weren't so many local tourist smoking and shouting at each other.


In the evening there was a great sunset.  Later on I caught a night train to Ninh Binh.
