How will I get there?

You must provide your own transportation to the city or town in which you will be working. You might want to ask the organization you will be working for for advice about nearby airports, trains, etc.

Will I need transportation once I arrive?

This depends greatly on the area in which you choose to work. Some host families will have a car you can use occasionally, or will be able to drive you when necessary, but in general, you will have to provide your own transporation. This means that if you do not have your own car that you can take with you and you are planning to work in an organization that is not accessible by public transportation, you must be able to find a host who has specified that s/he can drive you or let you borrow his/her car.
