Halong 2007

This is 'Dong Thien Cung' (Heavenly Cave), sometimes called Cave of the Dragon.  Formed by water seeping through the porous sedimentary rock, stalactites and stalagmites are everywhere in this huge cavern.  It is well lit with colorful lights, and there's lots of areas to explore.  That's our guide Huong on the left, and the penguin on the right is a refuse container.
