The walled Imperial City is probably the top travel destination in the city of Hue. It was the functioning royal palace well in to the 20th century. It's a huge complex dotted with smaller structures and is incredibly beautiful. The cobble stone walk ways and many walled structures give you the feeling of being taken back in time. MY favorite portion was a garden and pond area. It may have been the most peaceful place i've ever been. It was so enjoyable we high tailed it back to spend an extra 15 minutes there before the grounds closed. WE went late in the day which seemed to work out well as the tour groups had thinned out some.
