Fraser Island (K'gari) Great Walk

MODERATE // CHLG
Full Route Report

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).

Tregennis Coastal Walk

MODERATE // CHLG
Full Route Report

The Tregennis Peninsula offers some of the wildest and oldest coastal scenery in Wales. This stunning 6-mile (9.6km) circular walk starts from the tiny, fjord-like harbor of Porth Clais, just down the road from the city of St Davids. It traces the jagged perimeter of the peninsula along the Pembrokeshire Coast Path, gazing out over the ferocious tidal races of the Ramsey Sound towards Ramsey Island. The geology here is incredibly ancient (Precambrian volcanic rock), creating sharp, jagged headlands. The walk passes active sea-cliff farms, deep hidden 'geo's (inlets), the historic St Justinian's lifeboat station, and the dramatic ruins of a medieval copper mine right on the cliff edge.

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.

Full Scale Documentation
Route A // Hazard Verdict
Fraser Island (K'gari) Great Walk
MODERATE // CHLG
wildlife management (dingoes): K'gari is home to a genetically distinct population of wild dingoes. Habituation to human presence can lead to predatory or aggressive behaviors.
mechanical fatigue and thermal stress: Walking on sand increases muscular strain by 20-30% compared to hard surfaces. High humidity typical of coastal Queensland increases the risk of thermoregulatory failure.
Route B // Hazard Verdict
Tregennis Coastal Walk
MODERATE // CHLG
unguarded gales: Tregennis faces straight into the Atlantic and Irish Sea. In poor weather, the wind on the high cliffs can be strong enough to pose a literal blow-over risk.
cliff edge erosion: The path is rugged and runs very close to the sheer drops, particularly around the ruined copper mine at St Elvis.
