Arch over the sea

Photo from incredible Ha Long Bay or Descending Dragon Bay which is a popular and spectacular destination in Vietnam full of limestone isles and karst rocks popping out of the sea. A UNESCO World Heritage Site with more than 1960 isles of most various forms and full of caves and even lakes it truly is a spectacular sight with its nature, floating villages and even some inhabitants that had never set foot on mainland shores.
