The Pen y Fan Horseshoe

SERIOUS // HIGH CONSEQUENCE
Full Route Report

Pen y Fan is the highest peak in South Wales (886m) and the crown jewel of the Brecon Beacons National Park. While thousands stream up the 'tourist path' from the Storey Arms every day, the true mountaineer's route is the Beacons Horseshoe starting from the Neuadd Reservoir. This challenging 10-mile (16km) circular route climbs steeply onto the Craig Fan Ddu ridge, walks the long, grassy skyline over four peaks—including the 'diving board' rock at Fan y Big, Cribyn, Pen y Fan itself, and Corn Du—before descending back to the valley. It provides magnificent 360-degree views over the sheer, glaciated northern faces of the peaks down into the emerald Welsh valleys.

Piuquenes Pass (Andes Crossing)

LETHAL // NO-MARGIN
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.

SERIOUS // HIGH CONSEQUENCE

LETHAL // NO-MARGIN

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.

Full Scale Documentation
Route A // Hazard Verdict
The Pen y Fan Horseshoe
SERIOUS // HIGH CONSEQUENCE
steep undulations: While the main ridge looks flat on a map, the saddles (bwlchs) between the peaks drop sharply and require steep, rocky climbs back up the other side.
weather exposure: The open, grassy ridges offer absolutely zero shelter against the prevailing westerly winds and driving rain.
Route B // Hazard Verdict
Piuquenes Pass (Andes Crossing)
LETHAL // NO-MARGIN
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.
