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 Valley of the Rocks is one of Exmoor's most famous and striking geological features. This very popular 3.8-mile (6km) circular walk starts in the picturesque Victorian cliff-top town of Lynton. The outward leg follows a relatively flat, fully paved section of the South West Coast Path, carved directly into the sheer cliff face high above the Bristol Channel. Upon reaching the Valley—a surreal, dry U-shaped valley littered with massive, jagged gritstone rock formations (tors) and a resident herd of feral goats—the route loops back inland via the higher ground of Hollerday Hill. It is a walk of immense, dramatic coastal views requiring very little sustained climbing.
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.
