The K'gari (Fraser Island) Great Walk is an 8-day through-hike covering approximately 90km point-to-point within the Great Sandy National Park, Queensland. The route traverses often described as one of the largest sand island, moving through diverse ecological zones including high rainforests established on deep-sand substrates, mangrove systems, and freshwater perched lakes. Surface conditions are consistently sand-based, transitioning between consolidated forest paths and uncompacted dune segments. The route provides a cross-section of the island's unique hydrology and mature Satinay (Syncarpia hillii) timber stands. Access is regulated by Queensland Parks and Wildlife Service (QPWS).
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.
