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).
This magnificent 5.3-mile (8.5km) section of the South West Coast Path links two of North Cornwall's most dramatic locations: the mythical ruins of Tintagel Castle (legendary birthplace of King Arthur) and the historic, fjord-like harbor of Boscastle. The route is defined by the raw power of the Atlantic Ocean crashing against towering slate cliffs, deep rocky coves, and sweeping headlands. Along the way, you pass the stunning Rocky Valley—where a river has carved a spectacular gorge through the slate—and sweeping views out to Lundy Island. The constant, steep descents and ascents out of the coastal valleys (known as "coombes") make this short distance surprisingly strenuous.
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.
