Though best known for his adventure novels and humorous stories, Twain was a passionate world traveler and he recorded his journeys in several travel books which were all very popular at the time: "The Innocents Abroad" humorously chronicles Twain's "Great Pleasure Excursion" on board the chartered vessel Quaker City through Europe and the Holy Land in 1867. "Roughing It" follows the travels of young Mark Twain through the Wild West during the years 1861-1867.

"Old Times on the Mississippi" is a short account of Twain's experiences as a cub pilot, learning the Mississippi river. "A Tramp Abroad" details Twain's journey through central and southern Europe with his friend. As the two men make their way through Germany, the Alps, and Italy, they encounter situations made all the more humorous by their reactions to them. "Life on the Mississippi" is a memoir by Mark Twain of his days as a steamboat pilot on the Mississippi River before the American Civil War, recounting his trip along the Mississippi River from St. Louis to New Orleans after the War. "Following the Equator" - In an attempt to extricate himself from debt, Twain undertook a tour of the British Empire in 1895, a route chosen to provide numerous opportunities for lectures in English.
