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.
Westray North Coast — Noup Head Loop
Located on Westray, one of the northernmost Orkney Islands, this coastal circuit offers a wild, remote walk culminating at the spectacular Noup Head Lighthouse. The route takes you along towering 76-meter sea cliffs that plunge straight into the swirling Atlantic, offering views of geos (narrow rock inlets), natural arches, and dramatic sea stacks. It is most famous as an RSPB nature reserve: during the early summer, the cliffs are a chaotic, deafening 'seabird city' home to tens of thousands of guillemots, razorbills, kittiwakes, and puffins.
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.
