Just your own little self: Preah Palilay

Deep in the forest (actually only a 5 to 10 minute walk from the road and the Terrace of the Elephants, but I'm exaggerating), is a crumbling temple that no one visits.

Preah Palilay is always deserted of tourists — just you, the droning of the cicadas, and the chirping of the birds. There's a nearby Buddhist monastery, so you'll see the occasional passing monk, but absolutely no tourists.
