Just over an hour’s drive from the vibrant heart of Madrid, in the very center of the Alcarria region, lies a land of striking contrasts where time seems to slow down. Here, the emerald, almost still waters of the Entrepeñas reservoir meet the rugged, wind-carved limestone cliffs, creating landscapes worthy of an artist’s canvas. In this picturesque and secluded corner of Guadalajara province is hidden one of the most thrilling adventures for those seeking not just relaxation, but a real test of their limits and a chance to connect with nature on its own terms. This is the via ferrata “Pasta del Diablo” (Boca del Infierno).
A trail for the brave-hearted
The route, expertly designed by engineers in the Sacedón municipality, does not require professional mountaineering skills or superhuman endurance. Rated as K3 in difficulty, it is accessible to most people in good physical shape and, most importantly, without a paralyzing fear of heights. This is not a leisurely stroll in the park, but a serious challenge that takes about three hours and offers incomparable emotions, freeing the mind from urban stress. The journey begins with a vertical ascent on cold steel rungs securely anchored into the warm rock. With each meter of elevation, the world below shrinks to the size of a toy map, while the horizon expands, unveiling breathtaking views of the reservoir and gentle hills dotted with sparse vegetation. The sensation of complete control over your body, mixed with vulnerability to the power of nature, takes hold from the very first minutes.
Above the water: bridges and flights
The real test of endurance and self-control begins where the relatively simple vertical ascent ends. Participants must cross four suspension bridges, each one an adventure and challenge of its own. Imagine an unsteady structure of stretched cables and wooden planks dangling over a blue abyss that mirrors the sky. Every step demands utmost focus, while sudden gusts of wind sweeping through the gorge intensify the experience. Next come horizontal traverses, forcing you to move along a sheer cliff, literally pressing against it, gripping onto ledges and staples, feeling like part of the rock. The highlight of the entire route—the emotional pinnacle—is a forty-meter zipline descent. It’s a moment of pure, unfiltered exhilaration: the wind whistles in your ears and you feel the flight as the ground drops away beneath you, with nothing ahead but endless space and shimmering water. It’s important to remember that throughout the journey, your safety is ensured by a continuous safety cable—the so-called “lifeline”—to which every participant is securely fastened with special equipment.
In harmony with nature and the law
The route’s creators have shown deep respect for the environment, ensuring not only visitor safety but also the preservation of the unique local ecosystem. Access to the via ferrata is strictly regulated and only permitted during a specific period—from August 15 to January 15. This significant restriction is in place to avoid disturbing rare birds of prey that nest on the cliffs and are protected by law. This approach exemplifies responsible tourism, where humans are merely guests in the world of wildlife. In addition, completing the route requires payment of a mandatory municipal fee. All proceeds are dedicated exclusively to maintaining the route in top technical condition and updating safety features as needed. Permits and payments can be arranged in advance and hassle-free online through the official Sacedón tourism portal. It is worth noting that local authorities take rule compliance seriously, and attempting to use the route without proper authorization can result in a substantial fine.
More than just climbing
For those just discovering the exciting world of via ferrata, several accredited companies operate in the region offering professional guide services and rental of all the required certified equipment: helmets, harnesses, and special shock absorbers. Experienced instructors provide thorough briefings and accompany you along the entire route, making the adventure as safe and comfortable as possible—even for beginners. But Sacedón offers much more than a single trail. After a morning surge of adrenaline on the cliffs, you can completely change pace and set out on a peaceful, meditative journey by kayak or SUP across the mirror-like waters of the Entrepeñas Reservoir, exploring its secluded coves. This mix of activities allows you to plan a full-day program or even a whole weekend, turning a short trip into an unforgettable experience filled with vivid moments and discoveries in the very heart of Spain.
