Across the Llŷn (Wales Coast Path)
The Llŷn Peninsula Coastal Path is a remote, culturally distinct segment of the 1,400km Wales Coast Path. Stretching from the historic walled city of Caernarfon to the edge of Snowdonia at Porthmadog, the route circumnavigates a landscape where the Welsh language and maritime history remain deeply ingrained. The terrain transitions from the volcanic peaks of 'The Rivals' (Yr Eifl) and rugged granite cliffs to expansive, secluded sandy bays like Whistling Sands (Porth Oer). This is the sunniest corner of Wales, offering constant views of the Irish Sea and the sacred Bardsey Island (Ynys Enlli), the 'Isle of 20,000 Saints,' which marks the literal and spiritual apex of the journey.
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.
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.
