Discover some of the most unique sights in southern Spain on a day trip that takes you from the otherworldly landscape of Rio Tinto to the castle of Aracena. With the company of a knowledgeable guide, you can see how the long history of Andalusia has shaped the look of the region.

The day starts with a ride from Seville to visit Rio Tinto, a river famous for its rust-colored waters. For nearly 5,000 years, one civilization after another has mined the area for copper, silver, and gold, leaving a landscape that looks like the surface of Mars.

Next, head into the Sierra Morena mountain range for a visit to the town of Aracena, a paradise for those who want some freedom and tranquility. Follow some of the amazing trails through the nearby meadows, filled with cork trees, oaks, and Iberian pigs, and visit the Grutas de las Maravillas, a limestone cave almost 1.2 miles (2 km) long, before your return to Seville.
