'A Tramp Abroad' is a work of travel literature, including a mixture of autobiography and fictional events, by American author Mark Twain. The book details a journey by the author, with his friend Harris (a character created for the book, and based on his closest friend, Joseph Twichell), through central and southern Europe. While the stated goal of the journey is to walk most of the way, the men find themselves using other forms of transport as they traverse the continent.
