Some are job related where I've visited remote locations to check on resource sites or in conflict zones. Otherwise, I often go off the beaten track to find out what its like in remote areas. Originally for the landscapes, flora & fauna, now also to meet the people who live locally and to see how they live. Though I try very much not to be intrusive, exploited or voyeuristic about it, as I feel many westerners do that, still very much in the 19th Century tradition.

Its usually best to go on personal travel, though obviously more expensive and usually without a support network & connections that work often provides. For work or relief organizations it can be better, but you also may not have the easy option of leaving when it gets a bit dangerous, as can happen in some regions on very short notice.
