What 1880 travel book did Mark Twain write about a walking tour of Europe?

The 1880 travel book Mark Twain wrote about a walking tour of Europe is A Tramp Abroad.

The book combines travel narrative, autobiography, comic invention, and cultural commentary. Twain travels through central and southern Europe with “Harris,” a fictionalized companion based partly on his friend Joseph Twichell. Although the stated plan is to walk much of the route, the travelers also use trains, boats, and other transportation as they cross the continent.

The journey includes Germany, Switzerland, France, and Italy. Twain writes about Heidelberg, the Black Forest, the Alps, Lake Geneva, the Matterhorn, Venice, and Rome. His humor often comes from the gap between the confident American tourist’s assumptions and his actual confusion about European customs, languages, hotels, and institutions.

A common mix-up is The Innocents Abroad, Twain’s earlier travel book, published in 1869 after a voyage through Europe and the Holy Land. A Tramp Abroad is often treated as an unofficial sequel. It also contains “The Awful German Language,” a famous comic essay about the difficulties of German grammar, along with illustrations and unrelated humorous stories.
