Let me start off by saying that all tourists are visitors. A tourist is someone who visits far away places, usually to a place they are not familiar with. They might be on vacation, might not. A visitor is someone visiting a place. It might be the kid next door. It might be the old lady down the street. It might be the mayor of your hometown. They are not tourists, because they are not somewheres far away from their home, nor do they partake in tourism, which means to travel for pleasure. So, once again, all tourists are visitors, but not all visitors are tourists.

All tourists are visitors. Tourists 'visit' another place they are not familiar with, usually as vacation, and that place is usually far away from their home. A 'visitor' doesn't have to be a tourist. A 'visitor' could be your next door neighbor, or the old lady down the street, or the city mayor. All tourists are visitors, but not all visitors are tourists.
