Wildlife
History
Peña Cortada forms part of an ancient Roman irrigation canal composed of multiple tunnels and rock-cut sections, built to move water across the carbonate ridges for local agriculture.
Conservation
The area is sensitive to erosion and graffiti; stay on established paths, avoid climbing fragile masonry, and pack out all waste to help preserve the aqueduct and surrounding habitat.

Bring extra water
Carry at least 2–3 liters; summer shade is limited and exposed rock heats quickly.
Wear grippy footwear
Choose sturdy hiking shoes—short rocky steps and wet tunnel floors can be slippery.
Start early
Beginning at the meeting time avoids midday heat and gives better light for photos at Peña Cortada.
Respect tunnel spaces
The Roman canal tunnels are narrow with carved windows—move single-file and avoid touching fragile masonry.
Sturdy hiking shoes
Provide traction on rocky steps and stability on uneven trail sections.
Hydration system (2–3 L)
Essential for hot conditions—refill options are limited once you leave the villages.

Sun protection (hat, sunscreen)
Exposed limestone cuts offer little shade during midday.
