Ha Long Bay
Approximately two thousand islands packed together, like buildings in a city, bring travelers to see Ha Long Bay. What's more impressive than the sheer number of islands, is the geology of them: hundred foot rock faced cliffs staring down at the water in all directions. Seawater (and ice) carved stone walls, like art pieces, from millions of years of erosion. This is the UNESCO World Heritage Site, the decsending dragon of northern Vietnam. Ha Long Bay.
