This is a very small island and you can walk anywhere in a day. Because outside visitors are so rare, you'll attract a lot of attention from locals, who may follow you and expect a tip, although they will be friendly. Santo António is the capital, with similar architecture to São Tomé, if more run down. It is about the size of a large European village, and there are several reasonably priced pensãos.Air São Tomé e Príncipe has four flights a week between the islands, and there are infrequent ferries.
