There are many ways to travel around the world and one way is to volunteer as you go. Check the internet for help as there are sites dedicated to providing information on volunteering opportunities around the world. One such site is http://www.gonomad.com/
When you are considering volunteering it is a good idea to thoroughly research the organization and location you wish to visit. As much as you might be prepared to live in rough conditions you need to know that you will be safe, and, have somewhere to sleep and something to eat. The work also needs to be organized otherwise you can find yourself putting in a lot of work for a project that is disorganized and not even a priority for the local community.
You can find many blogs on the internet by people who are blogging as they are volunteer. You can read first hand experience and ask questions directly related to the place you want to volunteer.
