8Las Médulas, León

Imagine a landscape of jagged red peaks and deep green chestnut forests—this is Las Médulas, once the largest gold mine of the Roman Empire.

Located in León, the area is now a UNESCO World Heritage Site, offering surreal hiking trails that weave through red clay mountains shaped by centuries of mining. The contrast of fiery rock and lush greenery makes it one of the most dramatic landscapes in Spain, yet it rarely features in typical travel itineraries.
