For the duration of your journey, you will be living out of whatever you pack inside of your bag. Everything will be in there: your wallet, clothes, emergency supplies and identification papers. With that in mind, remember that you will be carrying that one item with you throughout the duration of your travels. Keep it light and keep it stocked with the essentials: make sure you carry plenty of cash, paper copies of your passport, extra food and emergency communication devices, including flares and walkie-talkies. Depending on the type of adventure you are trying to have, you may be able to leave extra luggage wherever you are sleeping overnight, but it's best not to pack too many clothing items as they can easily weigh you down.
