Tourists when scheduling a holiday often try to find unblemished list, but some travellers with courage for adventure do take that to extremes of any sense.

"The World Most Dangerous Places" is presently being updated by Adventurer and journalist Robert Young Pelton for a sixth edition.

"I wrote it for myself five years ago before the Iraq war and it's now being sold as a travel guide. I'm baffled, really. Now all my friends have been to Iraq and Afghanistan", he said.

Some shield them as learning and important in accepting the disaster, while others uncover the thought of rubber-necking at other's hardship crass and unfeeling to the people trying to restore their lives.

Martin Dunford, co-founder of Rough Guides, says: "Disaster tourism is mainly voyeuristic -- it's a bit like the traffic slowing down to view a motorway pile-up. I think it would have been insensitive to visit New Orleans in the immediate aftermath of Hurricane Katrina, but we'd certainly encourage people to go there now".

Most of the tourists see lists of the sites as the World Trade Centre in New York and violent as Auschwitz concentration camp in Poland, as an excitement through melancholic interest.

Dunford says: "I guess it all depends on when you feel current events become history".

Normally such visitors have military experience or wish to help the situation by working with aid agencies; however, disaster tourism is a advernturous one and needs a zeal to be undertaken.
