Jake Barnes, an American newspaperman wounded in the war, spends his Paris nights in the cafés of Montparnasse with Lady Brett Ashley — the woman he loves and cannot have. Then the whole crowd heads south: trout fishing in the Pyrenees, then a week of San Fermín in Pamplona, where drink, jealousy and a nineteen-year-old matador break everything open.
Hemingway built the novel from his own trips of 1924 and 1925, and almost every stop can still be visited: the café on the Boulevard du Montparnasse, the inn at Burguete, the arcade café on Pamplona's main square, the bullring, the beach at San Sebastián and the Madrid restaurant where the book's last meal is eaten.
Between 1947 and 1950 Sal Paradise, a young writer from New Jersey, crosses America again and again — hitchhiking, by bus and in borrowed cars — usually in pursuit of his wild, magnetic friend Dean Moriarty. Jack Kerouac typed the story on a continuous scroll of paper in three weeks in April 1951, and it was published in 1957. Sal is Kerouac, Dean is Neal Cassady, and most of the trips really happened.
The route picks out the places the novel names, from a rainy false start on the Hudson to Mexico City and back to a New York street corner. The novel gives towns and streets rather than addresses, so most pins mark areas, not doors.
