What are cheap travel options for college students?

I am interested in traveling to do volunteer work, or studying abroad. From your experiences or what you know, what is my best option? I am a student who is getting through school with loans, so I am looking for a great experience (hopefully doing some kind of volunteer work) where I am able to travel abroad and learn. I will be a junior in college this fall semester.What are cheap travel options for college students?u could sign up with some ngo in your area or international ones. check oxfam, red cross, medicins sans frontiere. if your field of study is medicine then u can ask for attachment for practical experience in various hospitals abroad. u could arrange thru your school or write direct to the place u wanna be in
