Helmet: Essential for protecting against falling rocks and bumps along the route.
Harness and Lanyard: A climbing harness with a double lanyard specifically for via ferratas is necessary for safety. This will allow you to clip into the safety cables and remain secure at all times.

Good Hiking Shoes or Climbing Shoes: The route requires footwear that provides both stability and grip for the rocky surfaces.

Best Time to Visit

The best time to tackle the Boca del Infierno is from late spring through early autumn, typically May through October. During these months, the weather in the Pyrenees is generally mild, and the canyon remains accessible. But weather can change rapidly, and it’s essential to check forecasts before your trip. After heavy rain, the river swells, and conditions can become more treacherous, so avoid visiting during or right after storms.

In the winter, snow and ice can accumulate on the route, making it dangerous. Moreover, the shaded parts of the canyon can remain icy even in early spring, so caution is advised in cooler months.

Safety Tips and Precautions

Check the Weather: Due to the canyon’s location, weather can shift quickly, and wet conditions can make the rock face slippery. Don’t attempt the ferrata in rainy or stormy weather.
Stay Hydrated and Energized: The physical exertion of the route can be dehydrating, and with the concentration needed for the bridges and climbs, staying fueled is crucial.
Go with a Partner or Group: Although solo climbers often tackle this ferrata, it is better to go with at least one other person. It ensures there’s someone to assist in case of any issues along the way.
Respect the Natural Environment: The Boca del Infierno canyon is a fragile ecosystem, and it’s essential to leave no trace. Stay on the designated route to avoid disturbing local wildlife or causing erosion.
Consider Hiring a Guide: If you’re new to via ferratas, hiring a local guide could enhance your experience and provide valuable insights. Guides can ensure your safety and offer useful tips on navigating the more difficult sections.
