5Bardenas Reales, Navarra

Think Spain is all about green hills and Mediterranean beaches? The Bardenas Reales desert in Navarra will change your mind.

This semi-arid landscape of clay, gypsum, and sandstone looks like a slice of the American Wild West dropped into Spain. Its bizarre rock formations, canyons, and plateaus have made it a filming location for shows like Game of Thrones. Visitors can hike, cycle, or drive through this Martian-like terrain and experience a completely different side of Spain.
