My Son has what is arguably the best collection of Cham art and architecture in a natural setting in Vietnam. It is somewhat of an arduous journey to get out there, but is well worth the effort. It is easier to get there than going to Angkor and if you do visit My Son, you will have a taste of what Angkor must look like. Though some of the monuments were destroyed during the war or taken by thieves, what remains is still considerable. Many of the structures are overgrown with dense vegetation but you can still enter some of them.
