Unfortunately, Seville is located in a very flat region of Spain and does not have any mountains within its city limits. However, there are several mountain ranges nearby that you can visit for hiking and exploring, such as the Sierra de Aracena and Picos de Aroche Natural Park, Sierra de Grazalema Natural Park, and Sierra Nevada National Park. These locations are all within a few hours' drive from Seville and offer stunning mountain landscapes for outdoor enthusiasts to enjoy.
