Greyhound offers the North America Discovery Pass, which allows unlimited travel in the United States (and certain parts of Canada and Mexico) within any 7-, 15-, 30-, or 60-day period ($239 to $539, depending on length of the pass). You can also buy similar passes covering different areas (America and Canada, the West Coast of North America, the East Coast of North America, Canada exclusively), and international travelers can purchase international versions of these same passes, which offer a greater variety of travel periods and cost considerably less. Greyhound also has senior-citizen, military, children's, and student discounts, which apply to individual fares and to the Discovery Pass.
