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.
The Tregennis Peninsula offers some of the wildest and oldest coastal scenery in Wales. This stunning 6-mile (9.6km) circular walk starts from the tiny, fjord-like harbor of Porth Clais, just down the road from the city of St Davids. It traces the jagged perimeter of the peninsula along the Pembrokeshire Coast Path, gazing out over the ferocious tidal races of the Ramsey Sound towards Ramsey Island. The geology here is incredibly ancient (Precambrian volcanic rock), creating sharp, jagged headlands. The walk passes active sea-cliff farms, deep hidden 'geo's (inlets), the historic St Justinian's lifeboat station, and the dramatic ruins of a medieval copper mine right on the cliff edge.
Head-to-Head Metric Analysis
HikeMetrics Hazard Scale — Explanation
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.
