You have been asked to plan a 17-day tour across Spain for a visiting friend. You will suggest they visit a different autonomous community each day and recommend the most interesting place to visit within each community. As an example for the first day, you recommend they visit Córdoba in Andalucía to see the beautiful mosque built between the 8th-10th centuries and walk along the Guadalquivir river, finishing the day by eating salmorejo and Spanish omelette. You provide expressions and vocabulary to structure the itinerary suggestions.
