Backpacking
Backpacking is fast becoming a very popular way of traveling on a budget while retaining an almost limitless level of flexibility.
Backpacking is also referred to as hiking, trekking or camping (or all rolled in one).
It essentially requires carrying all the requirements of a tour, such as provisions and tackle, in a knapsack so that the traveler is by and large self-sufficient.
If planned right and in advance, a backpacker is able to cut costs to the minimum without compromising either the fun or the itinerary.
