If you’re interested in travel that can truly open your eyes to the world, try one of these tough tours.

There are plenty of unusual tours that can give you insight into the reality of others’ lives.

In Cambodia, there’s the Genocide Trail, which commemorates the two million killed during Pol Pot’s Khmer Rouge regime.

You’ll see skulls stacked high and can meet with survivors of the genocide.

Then there’s the “Poverty and Oppression tour” in India. This tour offers a glimpse into the lives of Indian street children, and the money you pay goes to help create opportunities for India’s street children.

There are also similar poverty tours in Brazil and Argentina.

But if that’s not intense enough, you could always take up Iranian President Mahmoud Ahmedinijad up on his offer to tour Iran’s Bushehr nuclear reactor.

As one commentator put it, it’s like a uranium-enriched Disney World–only a lot less fun.
