Of all the places I've visited in my travels, Humberstone, Chile would rate right near the top. An abandoned mining town in the Atacama, it is extremely well preserved and a UNESCO World Heritage Site.

I'd encourage anyone visiting the region to go there. It's not a busy place. Myself and my girlfriend were the only people there on the day we visited. Just don't miss the last bus back to Iquique. We nearly did. The thought of spending the night there was terrifying!
