El Caminito del Rey — The King's Path

LOW // ACCESS
Full Route Report

Once considered the most dangerous hike in the world, the Caminito del Rey (Little Path of the King) is now a spectacular, safe, and exhilarating walkway through the Gaitanes Gorge. The trail consists of steel-and-wood boardwalks suspended 100 meters high on the vertical limestone walls of the canyon. It was originally built in 1905 for hydroelectric workers and was completely restored in 2015 CE. The route offers scenic views of the Guadalhorce river, the high bridges spanning the gorge, and the fossils embedded in the ancient seabed rock.

EXTREME // LETHAL
Full Route Report

Following the historic path used by the Army of the Andes in 1817, this 6-day trans-Andean expedition traverses the central cordillera from Mendoza, Argentina, to the Cajón del Maipo in Chile. The route crosses two significant high-altitude barriers—Portillo Argentino (4,330m) and Paso Piuquenes (4,030m). Hikers move through a high desert landscape of volcanic rock, vast glacial valleys, and the powerful Tunuyán River. The terrain consists primarily of rocky mountain paths, loose scree on the steeper pass approaches, and high-altitude plateaus where exposure to wind and sun is constant.

EXTREME // LETHAL

The HikeMetrics Hazard Scale is a proprietary 5-point classification system that evaluates hiking routes across five dimensions: physical demand, technical complexity, altitude exposure, weather risk, and rescue accessibility.

Unlike generic star ratings, the Hazard Scale is calibrated against altitude profiles, elevation gain per day, and logistical isolation factors — making it the most precise route classification system available.

Route A // Hazard Verdict
El Caminito del Rey — The King's Path
LOW // ACCESS
extreme vertigo exposure: Even though the trail is perfectly safe, the psychological impact of being suspended on a cliff can be intense.
heat reflection canyon: The Gaitanes gorge is a south-facing limestone oven; temperatures can soar above 40°C in July/August.

EXTREME // LETHAL
acclimatization_and_ams: Prolonged exposure above 4,000m poses a risk of Acute Mountain Sickness (AMS).
river_crossings: The Tunuyán River involves significant water volume and current strength, particularly in the afternoon.
