Hemingway loved to fish, and on his fourth trip to Pamplona he did some trout fishing in the Irati River in the Pyrenes.
After the Festival of San Fermin he and Hadley, Robert McAlmon, and the Smiths went into the mountains in Basque country around Burquete to relax a bit after the bullfights. Hemingway fished with worms as bait while the party had wine and cheese as they tried their luck.
This little day trip is a famous scene in "The Sun Also Rises."
