I averaged about $25 USD per day, including airfare, equipment and enough money to visit the local attractions and have some fun. It was possible to tour for as little as 3 dollars per day, if I bush camped, cooked my own food (or restaurants in undeveloped countries), filtered my own drinking water, and washed my laundry by hand. Unless I was near a city, which was seldom, this is what I had to do. View the detailed expense report and the pre-trip estimate.
