Border Crossing Wiki is a site dedicated to border crossings worldwide. Some border crossing are a relatively simple process, while some are an absolute pain. The project covers information on land border crossings, airports and sea ports. As this is a wiki site anyone can add to the database and help build the pool of knowledge. The site features information on customs, visas, border tax, border control, and getting to the border.
